The measure of the largest angle in a triangle is twicec the measure of the smallest angle. The third angle is 10 degrees less than the largest angle. Find the measure of each angle.
------------------------
largest: 2x
smallest: x
third: 2x-10
=================
Equation:
2x + x + 2x-10 = 180
5x = 190
x = 38 degrees
---
largest: 2x = 76 degrees
smallest: 38 degrees
third: 2x-10 = 66 degrees
=============================
Cheers,
Stan H.
