Question

My answer is in the image, but I'm not feeling confident enough to think I did it right, if I did it wrong, could I please receive an explanation on how to do it? Thanks.

Answer 1

First part (to find mMON) is correct.

To find mPON, we can't assume the angle has been divided into two equal parts; so we need to apply the same procedure as on finding MON:

tan⁻¹(2/6) = 18.26°
