Question

determine the angle which is equal to four fifth of its complement ​

Answer 1

Answer:

15°& 75°

Step-by-step explanation:

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°.

Answer 2

Answer:

72 degree

Step-by-step explanation:

a complementary angle is equals to ninety degree. When you multiply ninety degree by 4/5 then you found the result equals to 72 degree
