Question 231409
let x = largest


"smallest angle of a triangle is 2 degrees more than 1/4 of the largest" ___ x/4 + 2


"middle angle is 2 degrees less than the largest angle" ___ x - 2


x + x/4 + 2 + x - 2 = 180 ___ the 2's cancel


multiplying by 4 ___ 4x + x + 4x = 720 ___ 9x = 720 ___ x = 80


substituting ___ 80/4 + 2 = 22


substituting ___ 80 - 2 = 78
