Meg constructed triangle poq and then used a compass and straightedge to accurately construct line segment os, as shown in the figure below, which could be the measures of angles pos and angle poq?

If on=8x-8,lm=7x+4,nm=x-5,and ol=3y-6

#7. m is the midpoint of pq, the diameter of the circle o is 13in. and rm = 4in. find pm find pq
