Let x represent the measurment of an acute angle in degrees. the ratio of the complement of x to the supplement of x is 2: 5. guess and check to determine the value of x. explain why your answer is correct.

Ratio of complement of x : supplement of x

2 : 5

⇒ 2 times the supplement of x will be equal to 5 times the complement of x

5 (90 - x) = 2 (180 - x)

450 - 5x = 360 - 2x

5x - 2x = 450 - 360

3x = 90

x = 30°

Complement of x = 90 - x = 90 - 30 = 60

Supplement of x = 180 - x = 180 - 30 = 150

Ratio:

60 : 150

60 : 30 : 150 : 30

2 : 5 (checked)

I think the answer is

2 : 5
