Question

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

Answer 1

Answer:

$\frac{11\pi}{30}$

Step-by-step 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

$\frac{11\pi}{30}$

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.
