Let O be the centre of a circle. Chord AB subtends an angle of 153°. Let P be the point of trisection on major arc AB closer to point B. Find the angle measure of AQP. This is from the 1999 AIMO.

Where's Q?

A random point on the minor arc AB. sorry for the misunderstandin.

I solved it about 4 hours ago. It’s not really that hard lol

You are right. 69 deg is pretty easy.
