Answer:
the reference angle is given by
sine = negative
cosine = positive
tangent = negative
Step-by-step explanation:
We have been given the angle
The angle lies in Quadrant IV. Hence, in order to find the reference angle, we can subtract this angle with
Therefore, the reference angle is given by
In Quadrant IV, cosine and secant functions are positive and rest trigonometric functions are negative.
Thus, we have
sine = negative
cosine = positive
tangent = negative
