The option that can be used to verify the trigonometric identity, [tex]tan\left(\dfrac{x}{2}\right)+cot\left(x \right) = csc\left(x \right)[/tex] is option C;

C. [tex]tan\left(\dfrac{x}{2} \right) + cot\left(x \right) = \dfrac{1-cos\left(x \right)}{sin\left( x \right)} +\dfrac{cos \left(x \right)}{sin\left(x \right)} =csc\left(x \right)[/tex]

What is a trigonometric identity?

A trigonometric identity is an equations that consists of trigonometric functions that remain true for all values of the argument of the functions

The specified identity is presented as follows;

[tex]tan\left(\dfrac{x}{2} \right)+cot(x)=csc(x)[/tex]

The half angle formula for tangent indicates that we get;

[tex]tan\left(\dfrac{1}{2} \cdot \left(\eta \pm \theta \right) \right) = \dfrac{tan\left(\dfrac{1}{2} \cdot \eta \right)\pm tan\left(\dfrac{1}{2} \cdot \theta \right)}{1 \mp tan\left(\dfrac{1}{2} \cdot \eta \right)\times tan\left(\dfrac{1}{2} \cdot \theta \right)}[/tex]

[tex]\dfrac{tan\left(\dfrac{1}{2} \cdot \eta \right)\pm tan\left(\dfrac{1}{2} \cdot \theta \right)}{1 \mp tan\left(\dfrac{1}{2} \cdot \eta \right)\times tan\left(\dfrac{1}{2} \cdot \theta \right)}=\dfrac{sin \left(\eta\right) \pm sin\left(\theta \right)}{cos \left(\eta \right) + cos \left(\theta \right)} = -\dfrac{cos \left(\eta\right) - cos\left(\theta \right)}{sin \left(\eta \right) \mp sin \left(\theta \right)}[/tex]

When η = 0, we get;

[tex]-\dfrac{cos \left(0\right) - cos\left(\theta \right)}{sin \left(0 \right) \mp sin \left(\theta \right)}=-\dfrac{1 - cos\left(\theta \right)}{0 \mp sin \left(\theta \right)}=\dfrac{1 - cos\left(\theta \right)}{sin \left(\theta \right)}[/tex]

Therefore;

[tex]tan\left(\dfrac{x}{2} \right)=\dfrac{1 - cos\left(x \right)}{sin \left(x \right)}[/tex]

[tex]cot\left(x \right) = \dfrac{cos(x)}{sin(x)}[/tex]

[tex]tan\left(\dfrac{x}{2} \right)+cot(x)= \dfrac{1 - cos\left(x \right)}{sin \left(x \right)} +\dfrac{cos(x)}{sin(x)}[/tex]

[tex]\dfrac{1 - cos\left(x \right)}{sin \left(x \right)} +\dfrac{cos(x)}{sin(x)}=\dfrac{1-cos(x)+cos(x)}{sin(x)} = \dfrac{1}{sin(x)}[/tex]

[tex]\dfrac{1 - cos\left(x \right)}{sin \left(x \right)} +\dfrac{cos(x)}{sin(x)}=\dfrac{1}{sin(x)}=csc(x)[/tex]

Therefore;

[tex]tan\left(\dfrac{x}{2} \right)+cot(x)= \dfrac{1 - cos\left(x \right)}{sin \left(x \right)} +\dfrac{cos(x)}{sin(x)} = csc(x)[/tex]

The correct option that can be used to verify the identity is option C

Step-by-step explanation:

Solve the inequality for x.

10x > 9(2x - 5) - 11

10x > 18x - 45 - 11

10x > 18x - 56

subtract 18x from both sides:

Using the definition of isosceles and equilateral triangles:

12. x = 77°; y = 58°; z = 122°

13. x = 60°; y = 120°; z = 60°

What are Equilateral and Isosceles Triangles?

All three sides and angles of an equilateral triangle are equal in measure. On the other hand, two sides and two base angles of an isosceles triangle are equal to each other.

12. x = 1/2(180 - 26) [based on the definition of isosceles triangle]

x = 1/2(154)

x = 77°

y = 1/2(180 - (90 - 26)) [based on the definition of isosceles triangle]

y = 1/2(180 - 64)

y = 1/2(116)

y = 58°

z = 180 - 58 [base angles of isosceles triangle are equal]

z = 122°

13. Each interior angle of an equilateral triangle is equal to 60 degrees.

Therefore, x = the measure of one interior angle

x = 60°

y = 180 - 60 [linear pair]

y = 120°

The base angles of the triangle that has two equal sides would be 60° [180 - 120]

Therefore:

z = 180 - 2(60)

z = 60°

A rectangular garage has a perimeter of 46 meters and an area of 130 square meters. What are the dimensions of the garage?

Answers

The length of the rectangular garage will be 13 while the width will be 10.

What is a rectangle?

A rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

The perimeter of the rectangle = 2( length + width).

It is known that,

Area of rectangle = length × width.

130 = L× W

L = 130/W

The perimeter of the rectangle = 2( length + width).

46= 2( L+ W)

L + W = 23

130/W + W = 23

130 + W² = 23W

W² - 23W + 130 = 0

W² -13W - 10W + 130 = 0

W(W - 13) -10(W - 13) = 0

(W - 13)(W - 10) = 0

W = 13,10

For W = 13

L = 23 - 13 = 10

For W = 10

L = 23 - 10 = 13

Let's say the bigger dimension is the length and the smaller is the width.

Length = 13 and Width = 10

Hence "The length of the rectangular garage will be 13 while the width will be 10".

Answer:

A.  56

Step-by-step explanation:

Let the three consecutive integers be:

xx + 1x + 2

Given:

The sum of three consecutive integers is 30 more than twice the smallest integer.

Create an equation with the given information and solve for x:

[tex]\implies x+(x+1)+(x+2)=2x+30[/tex]

[tex]\implies 3x+3=2x+30[/tex]

[tex]\implies 3x+3-2x=2x+30-2x[/tex]

[tex]\implies x+3=30[/tex]

[tex]\implies x+3-3=30-3[/tex]

[tex]\implies x=27[/tex]

Therefore, the three consecutive integers are:

27, 28 and 29.

So the sum of the first and last integer is:

[tex]\implies 27+29=56[/tex]

Answer:

a) 56 --- (27, 28, 29)

Step-by-step explanation:

Forming the equation,

→ x + (x + 1) + (x + 2) = 2x + 30

Now the value of x will be,

→ x + (x + 1) + (x + 2) = 2x + 30

→ x + x + 1 + x + 2 = 2x + 30

→ 3x - 2x = 30 - 3

→ [ x = 27 ]

The last integer will be,

→ x + 2

→ 27 + 2 = 29

Sum of first and last integer is,

→ x + (x + 2)

→ 27 + (27 + 2)

→ 27 + 29 = 56

Hence, required answer is 56.

The Vertical opposite angles are ∠1 = 141° ; ∠2 = 39° ; ∠3 = 141° ; ∠4 =39°

The given angle cover the whole circle which will have 360°

∠1 + ∠2 +∠3 + ∠4 = 360°

∠1 + 39° +∠3 + ∠4 = 360°

Vertically Opposite angle:

The angles formed opposite to each other by a transversal. Horizontal Angles (Vertically Opposite Angles)The opposing angles created by the junction of two lines are known as vertical angles or vertically opposite angles. A pair of angles that are vertically opposed to one another are always equal.

Hence, ∠1  = ∠3 and ∠2 = ∠4. So  ∠4 = 39°

∠1 + 39° +∠3 + 39° = 360°

Let x be the ∠1 and ∠3;

x + 39° +x + 39° = 360°

2x = 360° - 78°

2x = 282°

x = 141°

Now, we know all the angles with respect to Vertical opposite Angles  .

The student who can write more words per minute is Marcus because he writes at a speed of 1.3 words per second, that is, in one minute he writes 79.8 words while Rhys writes at a speed of 1.1 words per second and in one minute he writes 66.66 words.

How to identify which student writes faster?

To identify the speed at which students write we must divide the number of words the student writes in time (seconds) as shown below.

Marcus

40 words / 30 seconds = 1.33

Rhys

100 words / 90 seconds = 1.11

Using the information above, we need to multiply the number of words each student types per second by the number of seconds that equals one minute.

1 minute = 60 seconds

Rhys

1.11 * 60 seconds = 66.6

Marcus

1.33 * 60 seconds = 79.8

The measure of angle VUT is ∠VUT = 70°.

What are angles in a linear pair?

When two lines intersect at a single point, a linear pair of angles is formed. If the angles are adjacent to each other after the two lines intersect, they are said to be linear. The sum of the angles of a linear pair is always 180°. These angles are also referred to as supplementary angles.

In the given figure, ∠RVU and ∠UVT are in linear pair, so by using the property of angles in a linear pair, we can write

                ∠RVU + ∠UVT = 180°

                  120° + ∠UVT = 180°

                         ∠UVT = 60°

Now as we know the sum of all angles of a triangle is equal to 180°,

               ∠UVT + ∠VTU + ∠VUT = 180°.

                   60° + 50° + ∠VUT =180°

                       110° + ∠VUT = 180°

                        ∠VUT = 180° - 110°

                        ∠VUT = 70°

Hence, the measure of angle VUT is ∠VUT = 70°.

Answers

y = 6x  + 1 is the line of the equation which has a gradient of 6 and passes through the point (3, 19)

What is a gradient?

A straight line's steepness can be determined by looking at its gradient. A line's gradient does not have to be a whole integer and might be positive or negative. A line's gradient can either be uphill (positive value) or downward (negative value).

Here, we have

Equation of line

y = mx  + c

m = Slope of line = Gradient  = 6

= y = 6x + c

a line passes through (3, 19)

so, we find the value of c

= 19 = 6(3)  + c

= c = 1

Now, we put the value of c in the equation and we get

= y = 6x  + 1

Hence,y = 6x  + 1 is the line of the equation which has a gradient of 6 and passes through the point (3  19)

The cosine and sine functions are presented as follows;

(a) cosine function is; f(x) = 5·cos((4/3)·x - (13·π/27)) + 2.5

(b) f(x) = -5·sin((4/3)·x - 530/3) + 2.5

What is a sine function?

A sine function is a periodic function used bases on the sine of an angle.

(a) The cosine function is f(x) = a·cos(b·x - c) + k

Where;

a = The amplitude

The amplitude = (Max - Min)/2

Therefore;

a = (7.5 - (-2.5))/2 = 5

f = b/(2·π)

c = The phase shift

k = The vertical shift

The minimum is at x = 200° = (200/360)·(2·π) = 10·π/9

The period = 270° = 3·π/2

Frequency, f = 2/(3·π)

b = 2·π·f = 2·π×2/(3·π) = 4/3

When the function is at the minimum point, θ = π

Therefore;

(4/3)×(10·π)/9 - c = π

c = 13·π/27

k = The minimum value + a

Therefore, k = -2.5 + 5 = 2.5

The cosine function is therefore;

f(x) = 5·cos((4/3)·x - (13·π/27)) + 2.5

(b) The negative sine function is found as follows;

f(x) = a·sin(b·x - c) + k

b = 4/3

k = 2.5

Minimum point sin((4/3)200 - c) = 180

((4/3)200 - c) = 180

c = 260/3

Using a negative sign function, we get;

((4/3)200 - c) = 90

c = 530/3

The equation is therefore;

f(x) = -5·sin((4/3)·x -530/3) + 2.5

Answer:

simplify 8/6, and you get 4/3.

This is a coincidence, because this is a Pythagorean triple,

which means: opp = 4, adj = 3, hyp = 5

now, we can solve the rest easily

sin(0) = 4/5

cos(0) = 3/5

The cos, tan, sec, csc and cot of the angle θ in quadrant IV are 3/5, -4/3, 5/3, -5/4 and -3/4 respectively

How to find the trigonometric ratio of the angle?

Trigonometry is a branch of mathematics dealing with the relationship between the ratios of the sides of a right-angled triangle with its angles.

Given that: sin(θ) = -4/5 and θ is in quadrant 4.

Using this information, we can sketch the location of the angle θ in the quadrant (See the attached image). Therefore:

(a) cos(θ) = 3/5     (adj/hyp)

(b) tan(θ) = -4/3     (opp/adj)

(c) sec(θ) = 1/cos(θ) = 5/3

(d) csc(θ) = 1/sin(θ) = -5/4

(e) cot(θ) = 1/tan(θ) = -3/4
