Question from mary, a student:

The ratio of the measures of the three angles of a triangle is 2:5:8. What is the measure of each angle of the triangle?

We have two responses for you


2 + 5 + 8 = 15 so for every 15 degrees the smallest angle get 2 of them, the middle sizes angle gets 5 of them and the largest angle get 8 of them. What is the total of the measures of the angles in a triangle? How many fifteens is that?



So they are 2/15, 5/15 and 8/15 of the whole, which is 180 degrees.
Does this help?

Good Hunting!
