Question

please fast give me answer of this question

Answer 1

in triangle ABC angle C=90
thus B=180-90+30
=60
angle PCA=60
hope it helps

Answer 2

Answer:

In triangle ACB

we know angle A is 30 given in question

and Angle C will be 90degree as there is a thereom that that when triangle is formed with the help of diameter and all the three point of that triangle touches the circumference of the circle then angle which is not on the diameter is always 90 degree .

now

30+90+angle B=180(sum of all angles of a triangle is 180)

so angle B becomes 60 degrees
