Question 818645: The third angle in an isosceles triangle is 20 more than 2 times as large as each of the two base angles. Find the measure of each angle.
Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! A = third angle
B = either base angle
---
2B + A = 180
A = 2B + 20
---
2B + A = 180
2B + 2B + 20 = 180
4B = 160
---
B = 40 degrees
A = 100 degrees
