What is the Complementary angle of Angle 55°?

To find:

We have to find the complementary angle of Angle 55°

Solution:

Two angles are said to be complementary to each other if the sum of the two angles is 90°.

Let the required angle = a

55° $+$ a = 90°

a = 90° - 55°

So, the complementary angle of 55° is 45°.
