Question

One angle measure in an acute triangle is 38°. What could the measure of one of the other angles be?

Answer 1

acute triangle: all angles less than 90 degrees
basic rule for triangle: sum of all angles = 180
soooo...

Answer 2

angle A + angle B + angle C = 180

and
A and B and C are each smaller than 90

and A = 38

so B and C are at most...?

Answer 3

ie 89 and 53 work...
