### What is Meant by Complementary Angle?

In Maths, two angles are said to be complementary, when the angles add up to 90 degrees. The complementary angle need not be adjacent to each other, but its sum should be equal to 90 degrees. For example, 47° and 43° are complementary angles.

Example:

To find out another angle if one of the complementary angles is 60°

Solution:

We know that the sum of complementary angles is 90

Let the unknown angle be x

Thus,

60° + x = 90°

X = 90° – 60°

X = 30°

Hence, the unknown angle is 30°
