Tips:
Go one by one starting from the given info.
Let me give u a starting point.
angles 31, 44 are 108 degrees. and angle 37 is 120 degrees.
For example, since BQP is an eq. triangle, angles 3, 4, and 11 are 60 degrees. SO are angles 10 and 9. This means that angle 5 is 60 degrees
Keep on doing this and you will figure out the rest of the angles
