Question

6-
An angle is 8 times its complement. Find third angle.​

Answer 1

Answer:

80°.

Step-by-step explanation:

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°.
