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. Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! 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
etc
