Since this is a polygon with 6 sides, it has a total of 720 degrees.  So adding together all the angles, you get: (2x-50) + (x+40) + (x+20) + x + 150 + 80. Simplify.  5x+240. And since you know all the angles add up to 720 degrees, set it equal to each other.  5x+240 = 720 5x= 480 (720-240) x= 96 Finally, plug in x to get the rest of your answers.
