Answer:
Step-by-step explanation:
<em><u>Let's find out for which angle could </u></em><em><u> be the Reference angle.</u></em>
For this exercise it is important to remember the definition of "Reference angle".
A "Reference angle is defined" as the smallest angle that is measure between the terminal side of an angle and the x-axis.
In this case, you have the following Reference angle provided in the exercise:
It is important to know that:
1. If the angle is in the First Quadrant, then the reference angle and are equal
2. If the angle is in the Second Quadrant, then the reference angle is:
3. If the angle is in the Third Quadrant, then the reference angle is:
4. If the angle is in the Fourth Quadrant, then the reference angle is:
By definition, the angle is in the First Quadrant, therefore, you can say that
