Answer 2

☆ Solution ☆

Given :-

• An angle is complement of a 78° angle.

To Find :-

• The measure of the angle ?

Step-by-Step-Explaination :-

Let the angle complementary of 78° = x

As we know that :-

Sum of complementary angle = 90°

So,

78° + x = 90°

x = 90° - 78°

x = 12°

Hence,

The angle complementary of 78° = 12°.
