Question 1044651
One angle of a triangle measures 10 degrees more than the second. The measure of the third angle is twice the sum of the first two angles. Find the measure of the angle in the triangle that has the greatest degree. 
-------
Call them A, B & C
---
B = A + 10
C = 2*(A + B) = 2A + 2B = 2A + 2A + 20 = 4A + 20
-----
A + B + C = 180
A + A+10 + 4A+20 = 180
