The three angles in a triangle always add up to 180 degrees. If one angle in a triangle is 108 degrees and the second is 5 times the third, what is the smallest angles?

OpenStudy (anonymous):

the sum of the 2 angle is 180 -108=72 and we can write an equation to find the smallest angle (x) \[x+5x=72\] solving for x, giving us x=12
