Question

In triangle ABC, angle C = 3 times of angle B and angle C = two times of the sum of angle A and angle B​

Answer 1

Explanation:

let angle a be x

and angle b be y

angle c=3y

also angle c=2x+2y

from eqn1 and eqn2,we have

3y=2x+2y

2x+2y-3y=180(sum of angles in triangle is 180)

2x-y=180

y=180-2x
