Problem
If the degree measures of the angles of a triangle are in the ratio , what is the degree measure of the largest angle of the triangle?
Solution 1
The sum of the ratios is . Since the sum of the angles of a triangle is , the ratio can be scaled up to The numbers in the ratio represent the angles of the triangle. The question asks for the largest, so the answer is .
Solution 2
We can denote the angles of the triangle as , , . Due to the sum of the angles in a triangle, . The greatest angle is and after substitution we get .
