Mr. T's Find the Missing Angle

See directions below

You need to find x and the interior angles for the triangle.

Example:  If the three angles were 2x, x - 3, and 4x + 8
the equation (and subsequent steps) to solve would be: 
2x + x-3 + 4x + 8 = 180
7x + 5 = 180
7x = 175
x = 25
The angles would then be 50, 22, and 108
Note this add up to 180 as they should.  Check your work!!
