Find the reference angle of 113°
Answer:
Find the reference angle of 113°.
Find the reference angle of 113°.The reference angle is 67°.
Step-by-step explanation:
Reference Angle
The reference angle is the angle between the terminal side of the angle and the x-axis. It is always the smallest angle that you can make from the terminal side of an angle. The measure of the reference angle within the x-axis is always equal or less than 90°.
However, we have different ways in finding the reference angle depending on the quadrant where the angle lies.

Quadrant 1: The reference angle is the same as the angle.
Examples:
30° = 30°
90° = 90°
Quadrant 2: 180° – angle
Examples:
120° = 60°
175° = 5°
Quadrant 3: angle – 180°
Examples:
220° = 40°
190° = 10°
Quadrant 4: 360° – angle
Examples:
290° = 70°
315° = 45°
