In ABC, the measure of A is 36º. The

measure of B is three times the

measure of C. Find B and C.

$\large{\underline{\underline{Solution→}}}$

Let x = measure of angle C

Then, measure of angle A = measure of angle B = 2x

So, x + 2x + 2x = 180°

5x = 180°

x = 36°

So, ∠C = 36° ∠A = ∠B = 72°

${\boxed{\boxed{\rm{\pink{→\bar{∠C = 36° ∠A = ∠B = 72°}✔}}}}}$
