Question

In triangle ABC, the measure of angle B is three times that of angle A. The measure of angle C is 20 degrees more than that of angle A. How do you find the angle measures?

Answer 1

angle A + angle B + angle C = 180°

let angle A = x°

=> angle B = 3x°

angle C = 20+x°

x + 3x + 20+x = 180

5x + 20 = 180

5x = 160

× = 160 ÷ 5

= 32°

So the angle measures are : 32°,96° and 52°

hope this answer helps♡♡
