Question

If an angle of 11pi/30 radian is in standard position. What is the reference angle in radian?

Answer 1

`(11\pi)/(30)`

Explanation:

The reference angle is an acute angle that angle in standard position makes with the positive x-axis.

The given angle in radians is

`(11\pi)/(30)`

This angle is already acute and hence it is itself a reference angle.

The reference angle of any angle in the first quadrant is the same angle.
