the second angle of a triangle is twice as big as the first angle. The third angle is 18 degrees more than the first angle. What are the angles?
---------------------
1st angle: x
2nd: 2x
3rd: x+18
------------------------
Equations:
x + 2x + x + 18 = 180
4x = 162
x = 40.5 degrees
2x = 81 degrees
x+18 = 58.5 degrees
