Problema Solution

In a triangle, the sum of the interior angles is 180 degrees. If angle A is three times as large as angle B, and angles B and C sum to 90 degrees, what is the measure of each angle?

as the problem says: A=3B

                               B+C=90

                              A+B+C=180

We replace B+C in the las equation and we find A=90. You know that A=3b so that means B=30. And C=90-B=60
