In Exercises 10-13, use the following information.
Q is in the interior of LROS. S is in the interior of LQOP. P is in the interior of
LSOT. mLROT = 127°. mLSOT = 71°. and mLROQ = mLQOS = mLPOT.
Make a sketch and answer the following.
10. Find mLQOP 11. Find mLQOT 12. Find mLROQ
Let Q be in the interior of LPOR. Use the Angle Addition Postulate
to solve for x. Find the measure of each angle.
