What is the measure of angle SQR in the figure above?

(1) x = 40°
Knowing the value of x is not enough to find the value of angle SQR unless
we know that the triangles PQS and SQR are congruent.(Insufficient)

(2) y = 80°
If y=80, the angle QSR is 100 degree(sum of angles in a straight line is 180 degree)
Since the angles in a triangle sum up to 180, SQR = 180 - (100+30) = 50(Sufficient - Option B)

Shouldn't there be an assumption mentioned that P, S, R lie on the same line??
