Question

write angle which is 1/5 to complement
​

Answer 1

Hyy,

Given-----

=> x = (90-x)×1/5

=> 5x = 90-x

=> 6x = 90

=> x = 90/6

=> x = 15

Thus x = 90 - x = 90-15=75 degree.

Answer 2

Let the angle be x complement of x is

(90° − x)

One fifth of the complement angle is

(90° − x)/5

Given x = (90° − x)/5

⇒ 5x = 90° − x

⇒ 6x = 90°

⇒ x = 90°/ 6 = 15°

Hence (90° − x) = (90° − 15°) = 75°

Thus the angles are 15° and 75°.
