Question

in the given figure angle BAC is equal to angle q c a angle abc is equal to angle q a c p is a point on AC such that angle abc is equal to 30 degree then find angle Apb

Answer 1

answer 75 because sum of opposite angles in isosceles triangle is equal so 30+x+x =180
30+2x=180
2x=180-30
2x=150
X=150/2
X=75
