Question

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?

Answer 1

A=90
B=30
C=60

Answer 2

thank you

Answer 3

write an equation
a=3b
c=90-b
3b+b+90-b=180
3b+90=180
b=30
a=3b=90
b+c=90==>c=60

Answer 4

thank you
