Question

In a triangle pqr pq =pr and angle q=40 find angel p

Answer 1

Angle r=40 as if 2 opposite sides are equal then the opposite angles are also equal

Using angle sum property of triangle

Angle p+q+r=180

40+40+p=180

80+p=180

P=100

Answer 2

Answer:

Angel p is 70.

here

p=x×x×40=180

2X×40=180

2X=180-40

2X=140

X=140/2

X=70
