Lengths of similar triangles and similar polygons are proportional to each other so, answer to the question in image are-

a. ZY=20

b. X=20.8

c. 9miles

What are similar polygons?

similar polygons are the polygons in which all the corresponding angles are same. Hence, they have same shape. The ratio of sides in any two similar polygons are same. This concept of constant ratio of sides is useful in evaluating the length of sides.

a.    A/a=B/b=C/c = D/d

       WX/HI=ZY/JK

   ZY=20

b.  X=(2.4×39)/4.5

                  X= 20.8

c. If 5cm represents 2miles it implies 1cm represents

1cm=2/5

So, 22.5cm will represent

22.5cm=2/5×22.5

22.5cm=9miles

This means that 22.5cm track represents the distance of 9 miles on map

The midpoint of the segment with the following endpoints, (4, 2) and
(7, 6) is (5.5, 4).

How to determine the midpoint of a given segment?
The center point of a straight line can be located using the midpoint formula. We can use this midpoint formula to determine the coordinates of the supplied line's midpoint in order to discover its location on a graph. Assuming that the line's endpoints are (x₁, y₁) and (x₂, y₂), the midpoint (a, b) is determined using the following formula:
(a , b) ≡ (((x₁ + x₂)/2), ((y₁ + y₂)/2))

Let the line segment be AB having endpoints as A(4, 2) and B(7, 6);
also let the co-ordinates of midpoint be C = (a, b)
Using the given formula in the available literature,
(a, b) = ((4 + 7)/2, (2 + 6)/2)
Equating parts of the previous equation, we get,
a = (4 + 7)/2 = 11/2 = 5.5
b = (2 + 6)/2 = 4
Thus, the midpoint of the segment is (5.5, 4).

Answer: She needs approximately 142.5 pounds

Explanation:

From the information given,

A pound of fertilizer covers 39 square feet of lawn.

If the lawn measures 5557.4 square feet, then

the number of pounds of fertilizer that she needs to buy = 5557.4/39 = 142.4975

Rounding to the nearest tenth,

She needs approximately 142.5 pounds

Answer:

  6 ft

Step-by-step explanation:

You want the length of the short side of a 30°-60°-90° triangle, given the longest side is 12 ft.

A 30°-60°-90° triangle has side lengths in the ratios ...

  1 : √3 : 2

Here, the longest side is given as 12 ft, so we can multiply this set of ratios by 6 ft to find the lengths of all of the sides:

  1 : √3 : 2 = (6 ft) : (6√3 ft) : (12 ft)

The shortest side has length ...

  k = 6 ft

__

Additional comment

You can also use trig functions to find the length k:

  k/(12 ft) = cos(60°) = 1/2, or

  k/(12 ft) = sin(30°) = 1/2

  k = (1/2)(12 ft) = 6 ft

Then David will have:

Answer: 10 years.

All of the triangles are an isosceles triangle, which means that they have two congruent side, and two congruent angles.

The first triangle has ∠B as 56°, AB ≅ BC.

The angle opposite to AB and BC are therefore, congruent, which means that

∠A + ∠B +∠C = 180°

∠A + 56° + ∠A= 180° (∠A and ∠C are congruent)

2∠A = 180° - 56°

2∠A = 124

∠A = 62°

The second triangle has ∠C equal to 62°. Since ∠A and ∠Care the angle opposite to the congruent side, they are also congruent which means ∠A = 62°.

The fourth triangle which has an exterior angle of ∠C equal to 118° forms a linear pair, and are thus supplementary

∠C = 62°, and both ∠C and ∠A are the corresponding angles to the congruent sides, it follows that they are also congruent.

∠A = 62°.

Conclusion

The following triangles have m∠A = 62°, first, second, and fourth triangle.

Arrange them in Ascending order :

-8(4/7) < -8.2 < 25/3 < √70

What is  Ascending order?

When numbers are arranged in ascending order, they are done so from least to largest. We must first compare the numbers before we may arrange them in any order. Compare first, then order. Numbers arranged in ascending order: Determine how many digits each number has.

Given numbers,

√70 ,-8.2, 25/3, -8(4/7)

We have to Arrange these in ascending order

First lets get these terms to its simplest form

Value of √70 = 8.36

value of 25/3 = 8.33

Value of -8(4/7) = -8.57

Now we have the simplest value of all the following numbers

That is:

8.36, -8.22, 8.33, -8.57

The smallest of all is -8.57

Then -8.57 will be at first

-8.57, 8.36, -8.22, 8.33

now the second will be -8.22

-8.57, -8.22, 8.36, 8.33

Now the third would be 8.33

So the last would be 8.36 that is the greatest

-8.57, -8.22, 8.33, 8.36

Now, for the original value it would be:

-8(4/7) < -8.2 < 25/3 < √70

The submarine descended at a constant rate to the current depth of -34 miles in 5 minutes. This means that the rate can be found by the formula:
= Current depth / Time

= -34 / 5
