Answer 2

Answer:

Let,

Angle A = x and Angle B = y

As mentioned in the question angle C = 3 angle B = 3y

Angle C is also given as 2(Angle A + Angle B) = 2(x+y)

So,

➟ 3y = 2(x+y)

➟ y = 2x

So angle C = 3y = 6x

We know that sum of all the 3 angles in a triangle = 180°

Therefore,

➟ Angle A+ Angle B + Angle C = 180

➟ x+ 2x+ 6x = 180

➟ x = 20

Hence,

Angle A = 20

Angle A = 20Angle B = 40

Angle A = 20Angle B = 40Angle C = 120
