Answer:
Step-by-step explanation:
join bc and od
now
oc=od=cd
cod is an equilateral triangle
angle cod is 60° (1)
also
angle acb =90 (angle in semicircle ) (2)
w.k.t
angle substended by any arc on circles boundry is equal to the half of angle substended by same arc on circle
2angle bcd =angle cod
by equation1
angle cbd =30 (3)
now
angle cbd +angle apb =angle acb ( ext.angle =int.angle in triangle)
by equation2 and 3
30+angle apb =90
angle apb =60
