The angle minor arc is of 150 degree
And in major arc is 30 degree
Solution
Just join AP and BP
it will form a equilateral triangle
So angle APB =60
the angle of triangle in circle is half to center so the angle sub's tended in major arc is of 30 and in quad. Sum of opposite angle is 180 so angle in minnor arc is 150
