Question

1. 315°

find the reference angle for the given angle. in the space provided, type the answer without any spaces between the letters, numbers, or symbols.

Explanation:

Step1: Identify quadrant of 315°

$270^\circ < 315^\circ < 360^\circ$, so it is in Quadrant IV.

Step2: Calculate reference angle

For Quadrant IV, reference angle = $360^\circ - \text{given angle}$
$360^\circ - 315^\circ = 45^\circ$

Answer:

$45^\circ$
