Can explain how you get angle pqr as 129? I thought shoule be 50.87. Thks
pqr is obtuse angle so must take the angle of sine in the 2nd quadrant. Hope this helps

Hi the 129.1 is the obtuse angle PQR. Thought we are looking at acute angle PQR which is 50.87? So to find angle QPR= 180 - 27-50.87 correct?
