# Explementary Angles

## Explementary Angles

Explementary angles are two angles which add up to a full angle (360°).

## A Real Example of Explementary Angles

Angles of 240° and 120° are explementary angles.

240° + 120° = 360°

## How to Find an Explementary Angle

### Question

What is the missing angle θ below?

### Step-by-Step:

# 1

The 160° angle and θ are explementary angles.

160° + θ = 360°

# 2

Subtract the 160° angle from 360°.

θ = 360° − 160° = 200°

### Answer:

The explementary angle is 200°.
