Answer:
P=77, Q=60
Step-by-step explanation:
Angle BCA is 180-137=43. BCA and YAC are opposite interior angles, which are congruent, so YAC is also 43.
To find P, you just take 60+P+43=180 (straight line). So, P should be 77.
You can figure out Q by using the total degrees in a triangle, 180. You have the other two angles now (43 and 77), so Q is 180-43-77=60. Incidentally, this is also the opposite interior angle of XAB, which is equivalent to Q at 60.
