Question

How to solve sum no 9 from the attachment below??? It is urgent

Answer 1

Answer:P+Q+R=180

2P=R=Q

P+2P+2P=180

5P=180

P=36

So,P=36

Q=2*36=72

R=2*36=72

Answer 2

Answer:

Given

an isosceles triangle

Ang.Q=R=2P

Step-by-step explanation:

let the angle P=x

angle Q=2x

angle R=2x

angle P+Q+R=180° (angle sum property of a triangle)

x+2x+2x =180°

5x =180°

x=180°/5

x=36°

angle P=x=36°

angle Q=2x= 2×36°=72°

angle R=2x=2×36°=72°
