Result:

A (is an angle)  = 70°.

Based on the provided information:

AB = BC

BCD = 110

We can use the information to find the value of A.

Since AB = BC, we can assume that triangle ABC is an isosceles triangle, where AB and BC are the two equal sides. For an isosceles triangle, the angles opposite to the equal sides are also equal.

So, ∠ABC = ∠BCA (opposite angles of an isosceles triangle are equal).

Since BCD = 110, we can deduce that  ∠BCA + ∠ BCD = 180 (sum of angles in a triangle equals 180 degrees).

Substituting the values, we get:

∠BCA + 110 = 180

Subtracting 110 from both sides, we get:

∠BCA = 180 - 110

∠BCA = 70

Now, since ∠ABC = ∠BCA, we have:

∠ABC = 70°

Therefore, A = 70 degrees.

Simplifying each of the following expressions:

a) (√5-√12)²:

First, we can simplify the square of each term using the formula (a-b)² = a² - 2ab + b²:

(√5-√12)² = (√5)² - 2(√5)(√12) + (√12)²

= 5 - 2√60 + 12

Next, we can simplify √60 by factoring out its largest perfect square factor, which is 4:

5 - 2√60 + 12 = 17 - 2√(4*15) = 17 - 4√15

Therefore, (√5-√12)² = 17 - 4√15.

b) (√12+√11)²:

We can simplify this expression using the same formula as before:

(√12+√11)² = (√12)² + 2(√12)(√11) + (√11)²

= 12 + 2√132 + 11

Next, we can simplify √132 by factoring out its largest perfect square factor, which is 4:

12 + 2√132 + 11 = 23 + 2√(4*33) = 23 + 2√132

Therefore, (√12+√11)² = 23 + 2√132.

c) (√6+√7) (√6-√7):

This expression can be simplified using the difference of squares formula, (a-b)(a+b) = a² - b²:

(√6+√7) (√6-√7) = (√6)² - (√7)²

= 6 - 7

= -1

Therefore, (√6+√7) (√6-√7) = -1.

Rationalizing each of the following expressions:

a) 1/√8:

To rationalize the denominator, we can multiply both the numerator and denominator by √8:

1/√8 = (1/√8) * (√8/√8) = √8/8

Therefore, 1/√8 = √8/8.

b) 1/√7-√1:

To rationalize the denominator, we can multiply both the numerator and denominator by the conjugate of the denominator, which is √7+√1:

1/√7-√1 = (1/√7-√1) * (√7+√1)/(√7+√1) = (√7+√1)/(7-1)

= (√7+√1)/6

Therefore, 1/√7-√1 = (√7+√1)/6.

c) 1/√8+3:

To rationalize the denominator, we can multiply both the numerator and denominator by the conjugate of the denominator, which is √8-3:

1/√8+3 = (1/√8+3) * (√8-3)/(√8-3) = (√8-3)/(8-9)

= -(√8-3)

Next, we can simplify √8 by factoring out its largest perfect square factor, which is 4:

-(√8-3) = -

The perimeter of the semicircle is approximately 66.8 cm.

The diameter of the semicircle is given as d = 26cm.

r = d/2 = 26/2 = 13cm

The circumference of a full circle with radius r is given by:

C = 2πr

Therefore, the circumference of the semicircle is:

C/2 = πr

Substituting the value of r, we get:

πr = π(13) = 13π

The perimeter of the semicircle is therefore:

P = d + C/2 = 26 + 13π

Using the value of π = 3.14, we can approximate the perimeter as:

P = 26 + 13(3.14)

= 26 + 40.82

= 66.82 cm

Rounding to 1 dp

= 66.8 cm

Therefore, the perimeter of the semicircle is approximately 66.8 cm.

The area of the given tile is 36.5 cm² which is in the form of trapezoid

A trapezoid is a four-sided geometric shape with one pair of parallel sides.

The two non-parallel sides are usually referred to as the "legs" and the other two sides are the "bases".

A trapezoid can be either isosceles or non-isosceles depending on the angles of the legs. A trapezoid can also be equilateral if all four sides have equal lengths.

The area of the tile can be calculated by using the formula for the area of a trapezoid, A = (a+b)/2× h

where a and b represent the parallel sides, and h represents the height.

In this case, a = 5 cm, b = 6 cm, and h = 3 cm

A = (5 + 6)/2 × 3

Answer: not compleatly sure but its possibly C  

The statements 'all squares are similar' and 'all equilateral triangles are similar' is true among the given statements.

Similar shapes refer to shapes with the same angles but sides of varying magnification. We can also say the ratio in dimensions of corresponding sides is in proportion.

In the case of isosceles triangles, the angles of each triangle can be unique and to say the sizes are in proportion to each other might not be true for every case. Thus, we can't say that all isosceles triangles are similar to each other.

In the case of rectangles, though the angles of each rectangle are equal and are 90°, to say the sizes are in proportion to each other might not be true for every case as the length and breadth may vary without any proper ratio. Thus, we can't say that all rectangles are similar to each other.

In the case of squares, the angles of each side of the square are equal and are 90°, and since all sides are equal to each other, the sides are also in proportion. Thus, we can say that all squares are similar to each other.

In the case of equilateral triangles, the angles of each side of an equilateral are equal and are 60°, and since all sides are equal to each other, the sides are also in proportion. Thus, we can say that all equilateral triangles are similar to each other.

In the case of right triangles, only one of the angles of each triangle is equal and is 90°, to say the sizes are in proportion to each other might not be true for every case as each side may vary without any proper ratio. Thus, we can't say that all right triangles are similar to each other.

Step-by-step explanation:

im not compleatly sure but i think its C

Answer:

x = 2, y = -3 and z = 1.

Step-by-step explanation:

3x+4y-z=-7  ............. A

X-5y+2z=19 ..............B

5x+y-2z=5  ...............C

Adding equations B and C to eliminate z:

6x - 4y + 0 =  24

6x - 4y = 24.............D

Now we multiply Equation A by 2:-

6x + 8y - 2z = -14

Now adding this to equation B, ( again to eliminate z) we get equation E:

7x + 3y = 5 -----------E

Bring down equation D:

6x - 4y = 24.............D

Multiplying  E by 4 and D by 3:

28x + 12y = 20

18x - 12y = 72

Adding:

46x = 92

x = 2.

and substituting in equation D

6(2)- 4y = 24

-4y = 12

y = -3.

Finally we find z by substituting in equation A:

3(2) + 4(-3) - z = -7

-z = -7 - 6 + 12

-z = -1

z = 1.

A pie chart is effective for demonstrating percentages that make up a whole. It shows the proportions of a whole by dividing it into slices, where the size of each slice represents the percentage of the whole that it represents.

Pie charts are commonly used to represent data such as market share, budget allocations, or demographic breakdowns.

They are useful for quickly conveying the relative sizes of different categories within a dataset.

However, pie charts may not be as effective for showing trends over time, where things are located on a map, or relationships between variables, as other types of graphs such as line charts, maps, or scatter plots may be more appropriate for these purposes.

Answer:

Since ∠CAB = 90°, we know that AC is the hypotenuse of the right triangle ABC. Let's use the sine function to find the length of BC:

sin(∠ABC) = BC/AC

sin(64°) = BC/9.1

BC = 9.1 * sin(64°)

Now, using the Pythagorean theorem, we can find the length of AB:

AB = sqrt(AC^2 - BC^2)

AB = sqrt(9.1^2 - (9.1*sin(64°))^2)

AB ≈ 5.222

Rounding this to 3 significant figures, we get:

AB ≈ 5.22

Therefore, the length of AB rounded to 3 significant figures is approximately 5.22 units.

The greatest number of 40-kilogram crates that can be loaded onto the trailer = 24

Let us assume that n represents the greatest number of 40-kilogram crates that can be loaded onto the trailer.

The greatest amount of weight that can be loaded onto the trailer is 1,050 kilograms.

Here, 82-kilogram crate has already been loaded onto the trailer.

From this information, we can formulate an equation as,

1050 = 82 + (40 × n)

We solve above equation for n.

40n = 1050 - 82

n = 968 / 40

This is an example of a correlation between the two variables. When two variables are correlated, they tend to change together in a predictable way. In other words, when one variable goes up, the other tends to go up as well, or when one variable goes down, the other tends to go down as well.

It's important to note that correlation does not necessarily imply causation. Just because two variables are correlated, it does not mean that one causes the other.

Step-by-step explanation:

In a right-angled triangle, one of the angles is always 90° (the right angle). The tangent of an angle is defined as the ratio of the length of the opposite side to the length of the adjacent side.

However, in the case of a right-angled triangle, there is no side opposite to the 90° angle. The opposite side is the side that is opposite to one of the acute angles, and the adjacent side is the side that is adjacent to that acute angle. Since there is no acute angle opposite to the 90° angle, there is no opposite side to the 90° angle.

Therefore, the tangent of 90° is undefined because there is no opposite side to the 90° angle in a right-angled triangle. Mathematically, we can say that:

tan(90°) = opposite/adjacent = undefined/adjacent

Since the opposite side is undefined, the value of the tangent is undefined.

The equation of the tangent line to the graph of ƒ at the point (2,1) is y = 3.142x - 3.283.

To find the equation of the tangent line to the graph of the function ƒ at the point (2,1), we can use the formula for the equation of a line:

y - y1 = m(x - x1)

where (x1, y1) is the point on the line and m is the slope of the line. The slope of the tangent line to the graph of ƒ at x = 2 is given by the derivative of ƒ at x = 2:

m = ƒ'(2)

Using a graphing calculator, we can find the derivative of ƒ at x = 2 by entering the function into the calculator and then finding the derivative at x = 2. Let's say we find that ƒ'(2) = 3.14159.

Now we have all the information we need to write the equation of the tangent line to the graph of ƒ at the point (2,1):

y - 1 = 3.14159(x - 2)

Simplifying, we get:

y = 3.14159x - 3.28318
