the second angle of a triangular parking lot is four times as large as the first angle. The third angle is 45 degree less than the sum of the other two angles. How large are the angles?
------------------
1st angle: x
2nd angle: 4x
3rd angle: 5x-45
-----------------------
Equation:
x + 4x + 5x-45 = 180
10x = 225
x = 22.5 degrees (1st angle)
4x = 90 degrees (2nd angle)
5x-45 = 67.5 degrees (3rd angle)
