Answer:

1 1/8

Step-by-step explanation:

19 7/8-18 3/4

change the 3/4 to 6/8 so they the same denominator then subtract:

19 7/8 - 18 6/8= 1 1/8 inches

Answer:

20 + 4 + 40 + 9

Step-by-step explanation:

20 + 4 is 24 and 40 + 9 is 49, so it's pretty much the same thing.

  To get the measures of the angles and the sides of a triangle we use sine rule,

Option B will be the correct option.

From the triangle given in the figure,

     Let the length of the string of the kite = l feet                    

     By applying triangle sum theorem in the given triangle ABC,

m(∠A) + m(∠B) + m(∠C) = 180°

75° + 45° + m(∠C) = 180°

m(∠C) = 180° - 120°

m(∠C) = 60°

      Now apply the sine rule in the given triangle ΔABC,

[tex]\frac{\text{sin}(B)}{AC}=\frac{\text{sin}(C)}{AB}[/tex]

[tex]\frac{\text{sin}(45^{\circ})}{l}=\frac{\text{sin}(60^{\circ})}{240}[/tex]

[tex]l=\frac{\text{sin}(45^{\circ})\times 240}{\text{sin}(60^{\circ})}[/tex]

[tex]l=\frac{\frac{1}{\sqrt{2}}\times 240}{\frac{\sqrt{3} }{2} }[/tex]

[tex]l=\frac{240}{\sqrt{2}}\times \frac{2}{\sqrt{3} }[/tex]

[tex]l=\frac{480}{\sqrt{6}}[/tex]

[tex]l=\frac{480}{\sqrt{6} }\times \frac{\sqrt{6} }{\sqrt{6} }[/tex]

[tex]l=\frac{480\sqrt{6} }{6}[/tex]

[tex]l=80\sqrt{6}[/tex]

Therefore, Option (B) will be the answer.

Here we want to use what we know about trigonometry to find the side of a triangle.

We will see that the correct option is B.

First, we know that the sum of all internal angles of a triangle is 180°.

Then the missing angle of the triangle, let's call it C, is given by:

A + B + C = 180°

75° + 45° + C = 180°

C = 180° - 45° - 75° = 60°.

Now we can use the sine rule, it says that the sine of an angle over the length of the opposite side of the triangle is a constant, then we have:

[tex]\frac{sin(A)}{BC} = \frac{sin(B)}{AC} = \frac{sin(C)}{AB}[/tex]

Here the length of the string is AC.

And we know that:

B = 45°

C = 60°

AB = 240

Then we can use the second and third parts of the above equality to get:

[tex]\frac{sin(45 \°)}{AC} = \frac{sin(60 \°)}{240}[/tex]

Now we can solve this for AC:

[tex]AC = \frac{sin(45 \°)}{sin(60 \°)}*240 = \frac{2 }{\sqrt{3*2}}*240[/tex]

Now we can multiply and divide by √6

[tex]AC = \frac{\sqrt{6} }{\sqrt{6} } *\frac{2}{\sqrt{6} }*240 = \frac{\sqrt{6} }{3}*240 = \sqrt{6} *80[/tex]

Then we can see that the correct option is B.

Step-by-step explanation:

Answer:

61

Step-by-step explanation:

The ratio of the short leg to the hypotenuse of the given triangle is 1:2

A triangle is a polygon of three sides. In a right angled traingle we use some basic trigonometric formula. Depending upon the  ratio of sides of triangle we use six trigonometric formulas.

The shorter leg of the triangle is =hypotenuse × cos60° .

[Use the formula cosθ=base/hypotenuse]

Therefore, the shorter leg= hypotenuse/2      [∵cos60°=1/2]

∴ (shorter leg)/(hypotenuse)=1/2

So, Shorter leg: Hypotenuse=1:2.

Hence the ratio of the shorter leg to the hypotenuse is 1:2.

Recall that the slope or gradient of a line segment through two points is the ratio of the change in the y coordinate to the change in the x coordinate.

If the gradient is 1, then

1 = (-3 - 4) / (a - 3a)

Solve for a :

1 = -7 / (-2a)

1 = 7/(2a)

2a = 7

a = 7/2

Answer:  Choice A.  [tex]\sqrt{35}[/tex]

=================================================

Explanation:

Recall that 36 is a perfect square

36 = 6^2

Or in other words, [tex]\sqrt{36} = \sqrt{6^2} = 6[/tex]

The point marked on this number line is some value smaller than 6, so the number under the square root must be smaller than 36.

That could apply to either choices A or B.

Using a calculator shows that

[tex]\sqrt{35} \approx 5.916\\\\\sqrt{30} \approx 5.477\\\\[/tex]

Choice A is the better answer as it's much closer to 6 than choice B is.

f(x)=-.5(-2) + 5

Step-by-step explanation:

The midpoint can be found with the formula.

midpoint = (x1+x2) /2 , (y1 + y2 )/2

 ( x1 , y1), and (x2 , y2 ) are the coordinates of two points, and the midpoint is a point lying equidistant and between these two points.

P = (0,0)

midpoint = (2,5)

x midpoint = 2 = (0+ x2)/2

×2 = 4

y midpoint = 5 = (y2+0 )/2

10 = y2

so the point Q is (4 , 10)
