Find the angle that completes 90°.

Complement (°) 55

Formula: complement = 90 − angle

Step-by-step with your numbers:

1. Values used:

2. Angle = 35 °

4. Complement = 55°

Did we solve your problem today?

Two angles are complementary when they add to 90°.

The math behind it

complement = 90° − the given angle.

35° → complement 55°.

Over 90°?

Then there's no complement (it would be negative).
