Given:
Given an angle 110 degrees.
Required: Its corresponding reference angle
Explanation:
When an angle is drawn on the coordinate plane with a vertex at the origin, the reference angle is the angle between the terminal side of the angle and the x-axis.
Sketch the given angle.
When the terminal side is in the second quadrant (angles from 90° to 180°), our reference angle is 180° minus our given angle.
The reference angle of 110° is 180° – 110° = 70°
Final Answer: Reference angle of 110° is 70°.
