bhai ... angle q = r it is property of iso.triangle so sum of both angle is q+r+p=180 . p=180-42-42. p=96°

it is an iosceles triangle
hence as given pq=pr
there fore angle r=q
now q=42
by asp
angle p=96
hence as given pq=pr
there fore angle r=q
now q=42
by asp
angle p=96

Given that PQ=PR
So,Angle R is equal to Angle Q=42°
We know that sum of all angles of a triangle is 180°
so, R+Q+P=180
so, 42+42+P=180
Therefore, P= 180-(42+42)
so, P=180-84
P= 96°
