Answer:

4 : 25

Step-by-step explanation:

Given the ratio of 2 similar figures = a : b, then

ratio of areas = a² : b²

Given the similarity ratio = 2 : 5, then

ratio of areas = 2² : 5² = 4 : 25

The ratio of two complementary angles is 5 to 1. what are the angles?
densk [106]
Call x and y those angles. If they are complementary, then their sum equals 90°:

x + y = 90°

y = 90° - x

The ratio of them is 5 to 1. So,

x/y = 5/1

x/(90° - x) = 5/1

x = 5 * (90° - x)

x = 450° - 5x

x + 5x = 450°

6x = 450°

x = 450°/6

x = 75°

The measure of the other angle is

y = 90° - 75°

y = 15°

The angles are 75° and 15°.

I hope it helps. =)
