Question 404259
I never learned "the five steps for problem solving" (lots of problems have way more than five steps...) but here's how you solve it.


Suppose angle B = b. Then, angle A = 3b + 6 (subject to the given condition). They are complementary, so 


b + (3b + 6) = 90


4b + 6 = 90


4b = 84 --> b = 21, so angle B = 21 and angle A = 69 (degrees)
