Question

In a triangle ABC, angle c=3 angle B =2(angleA+angleB). find the angles ​

Answer 1

20 ,40,120

Step-by-step explanation:

1)3angle B=2angle A+2angle B

angle B=2angle A

2)angle C=3angle B

let angle B be some x

angle c=3x

angle a=x/2

angle b=x

sum of all angles in a triangle =180

x/2+x+3x=180

4x+x/2=180

9x/2=180

x=40

angle a=x/2=20

angle b=x=40

angle c=3x=120
