Answer:

The measure of the reference angle is 45 degrees and sin(theta) =
√(2\\)/2

Explanation:

The angle 3
\pi/4 found on the unit circle is at the point (-
√(2\\)/2 ,
√(2\\)/2)

since the point is (cos, sin) sin(theta) =
√(2\\)/2

this angle is also equal to 135 degress

since it is in quadrant 2, 180-135 = 45 meaning the reference angle is 45

Unit circle:
