The measure of the middle angle of a triangle is twice the smallest angle. The sum of the middle angle and the largest angle is 5 times the smallest angle. Find the measures of the angles.
m = 2s
m + l = 5s or
2s + l = 5s which shows l = 3s
summed , the angles = 180
s + 2s + 3s = 180
s = 30 then l = 90 m = 60 degrees
