Question

Check all that apply. I is the reference angle for: 5 OA 6 O B. 6 OC. 13T 6 OD.

Answer 1

D and C.

Explanation:

5pi/6 and 13pi/6

Answer 2

π/6

Explanation:

A reference angle is a positive acute angle that represents an angle θ of any measure. This is the smallest angle formed between the terminal side of θ and the x-axis.

Since the angle π/6 is in the first quadrant, the reference angle is equal to the original angle, therefore it would be π/6

`\theta_R=(\pi)/(6)`
