Question 265011: One angle of a triangle is twice as large as another. The measure of the third angle is 20 degrees more than that of the smallest angle. Find the measure of each angle. Note: in the book it has a pic. 1st angle is x, 2nd is 4x, and the third is 5x. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! One angle of a triangle is twice as large as another.
The measure of the third angle is 20 degrees more than that of the smallest angle.
Find the measure of each angle.
------
1st: x
2nd: 2x
3rd: x+20
-----------------
Equation:
x + 2x + x + 20 = 180
4x = 160
x = 40 degrees
2x = 80 degrees
x+20 = 60 degrees
