Question

Use the unit circle to identify the reference angle for 395°

Answer 1

Solution:

Consider angle 395°. To find the reference angle for 395° we perform the following steps:

Subtract 360 from 395:

$395-360\text{ = }35$

The resulting angle of 35 is positive, less than 360, and coterminal with 395.

Since 35 is in the first quadrant, we can conclude that the reference angle is 35 degrees.
