The statement(s) that are true is that the measure of the reference angle is 45°.
<h3>What is the conversion of radians to degrees?</h3>The conversion of an angle in radian to a degree can be determined by the multiplication of the given angle in radian by 180/π.
From the given information:
To degrees, we have:
A reference angle is an angle that measures the remaining distance (called the terminal distance) to the x-axis.
315° is in the 4th quadrant, i.e.
= 360° - 315°
= 45°
Therefore, the statement(s) that is true is:
- The measure of the reference angle is 45°.
