How do I set the equation up?

OpenStudy (wolf1728):

The 2 angles for which you have to solve add up to 144 degrees. 360 degrees - 216 degrees = 144 degrees now to set up the equation

OpenStudy (wolf1728):

x-1 + x -71 = 144

OpenStudy (shaleiah):

108?

OpenStudy (wolf1728):

2x -72 = 144 2x = 216 x = 108 I think you are correct.
