Problema Solution

the largest angle of a triangle has a measure 22 degrees less than twice the measure of the smallest angle.  the measure of the other angle is 2 degrees more than the smallest angle.what is the measure of the largest angle?

Answer provided by our tutors

let 'x' represent the smallest angle, then '2x-22' represents the largest angle and 'x+2' represents the third angle


there are 180 degrees in every triangle, therefore:

180 = x + 2x-22 + x+2

202 = 4x + 2

200 = 4x

x = 200/4 = 50


2*50 - 22 = 78

50 + 2 = 52


the angles are 50, 52 and 78
