<PRE><B>Question 1031231</B>
We know that a triangle has 180 degrees. 
Angle A + Angle B + Angle C = 180
Let A be the smallest and C be the largest.
C = 2A - 30 (The measure of the largest angle is 30 degrees less than twice the measure of the smallest.)
B = A + 10 (And the measure of the middle angle is 10 degrees more then the smallest.)
Substitute what you know into the first equation.
A + B + C = 180
A + (A+10) + (2A-30) = 180
4A-20 = 180
4A = 200
A = 50
If A = 50, then B = 50+10, and C =2(50)-30
50 + 60 + 70 = 180
