The measures of two complementary angles are complementary angles are in the ratio 1: 3. what are the measures of the angles?

The measure of angles are 22.5 degree and 67.5 degree

Solution:

Given that, measures of two complementary angles are in ratio 1 : 3

one angle : another angle = 1 : 3

Let the first complementary angle 1x

Let the another complementary angle be 3x

If the angles are complementary, then their sum is 90 degrees

Therefore,

1x + 3x = 90

4x = 90

x = 22.5

Then, first angle = 1x = 1(22.5) = 22.5

Another angle = 3x = 3(22.5) = 67.5

Thus the measure of angles are 22.5 degree and 67.5 degree

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

sorry

sorry, but im pretty sure its a now that i look at it
