In triangle ABC angle A is three times as large as angle C T

In triangle ABC, angle A is three times as large as angle C. The measure of angle B is 25 degrees less than that of angle C. Find the measure of the angles.

Solution

Let angle C be C

So, Angle A = 3C

Angle B = C - 25

A+B +C = 180

3C + C -25 + C = 180

5C = 205

C = 41 deg

A = 3*41 = 123 deg

B = 16 deg
