Question

Find the value of the given trigonometric function by finding the reference angle x and attaching the proper sign.tan291 degreesWhat is the representation of tan 291 degrees using the reference angle x?

Answer 1

Solution

from the question,

The Reference angle is the angle between the terminal side of the angle and the x-axis

reference angle

$\alpha=360-291=69^0$

Hence the reference angle is 69
