Problema Solution
In a right triangle, one of the acute angles is 9 degree less than twice the other acute angle. Find the measure of each acute angle.
Answer provided by our tutors
A triangle has 180 degrees. We have a unknown number reference so we name it x.
180 = 90 (right angle) + x + 2x - 9 (unknown angles)
Simplify
90 = 3x - 9
99 = 3x
x = 33
Plug back in
2(33) - 9
57 & 33 ####
