The LessonExplementary angles are two angles which add up to a full angle (360°).
A Real Example of Explementary AnglesAngles of 240° and 120° are explementary angles.
240° + 120° = 360°
How to Find an Explementary Angle
QuestionWhat is the missing angle θ below?
The 160° angle and θ are explementary angles.
160° + θ = 360°
Subtract the 160° angle from 360°.
θ = 360° − 160° = 200°
Answer:The explementary angle is 200°.
