Question 213818
The first angle of a triangle is half the measure of the second angle. The measure of the third angle is 40 degress more than 4 times the measure of the first. Find the measure of each angle. 
------------------
Let the 2nd angle be "x".
Then the 1st angle is "2x"
And the 3rd angle is "4x+40"
-------------------------------
Equation:
x + 2x + 4x+40 = 180
7x = 140
x = 20 degrees (2nd angle)
2x = 40 degrees (1st angle)
4x+40 = 120 degrees (3rd angle)
