Qs is the diameter and apt is a tangents at p then find angle apq

Answer:
a. 60
Step-by-step explanation:
prolongate a line from Q to APT to form a 90 angle by calculation in triangle QSR angle Q is 30 then returning to APQ 30+30+x should equal to 90 where Q in APQ is 30 then 30+90+x=180 then x=60
