Answer 1

since the angle formed by line joining of diameter is always 90°. so the sum of angle P and Q must be left 90° . given P=2Q so let Angle Q be x so we get equation x+2x = 90 . after solve it we get angle p=60° and Q=30°

Answer 2

As an angle in a semicircle is 90 degree
so angle R =90
and as angle P =2×angle Q
and sum of angles in triangle is 180. it means
angle P+angle Q+angle R=180
2×angle Q+angle Q =180-90
3×angle Q=90
angle Q =30
as angle P =2×angle Q
angle P =2×30=60
so angle p=60
