Question

The angle which is equal to 8 times its complement is:

Answer 1

Let the one angle be x.
Then the other angle will be 8x.


We know that the sum of complementary angles is 90°.

Therefore, 
x + 8x = 90°
9x = 90°
x = 10.
And, 8x = 8 X 10 = 80°.

Hence, the angle which is equal to 8 times of its complement is 80°.

Answer 2

80 degree of its complement
