Question

for this special angle, draw the angle and find the reference angle: t=5pi/6

Answer 1

Given the measure of the following angle:

$t=\frac{5\pi}{6}$

The given angle lying between π/2 and π

So, the angle (t) lying in the second quadrant

The reference angle will be:

$\pi-\frac{5\pi}{6}=\frac{\pi}{6}$

So, the answer will be the following option:
