Answer:
In ΔPQR
60+ 30 +∠PRQ = 180 ( angle sum property of triangle )
90 + ∠PRQ = 180
∠PRQ = 180 - 90
∠PRQ = 90
∠PRQ+ ∠PRS = 180 ( Linear pair )
90 + ∠PRS = 180
∠PRS = 90
In another triangle whose complete name is not given by you
90 + 50 + x = 180 ( angle sum property of triangle)
140 + x = 180
x = 180 - 140
x = 40
