Question

In a triangle ABC, angle C =3, angle B =2 (angle A +angle B). Find the three angles..... ​

Answer 1

let the angle A be x

let angle B be 2x

Let angle C be 3x

so, we know the sum of all the angles of a triangle is 180 degree

therefore , we can write x+2x+3x=180degree

or, 6x = 180

or, x= 180/6=30

so angle A = x=30 degrees

angle B = 2x = 2×30=60 degree

angle C = 3x = 3×30 = 90degree

so alltogether 30+60+90=180 degree

so angles are 30degree, 60degree, 90degree.

THANKS.
