Pie over 3 is the reference angle for

Step-by-step explanation:

Let's find out for which angle   could    be the Reference angle.

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  

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

is means division by fractions
