easy as pi(math joke. lawlers). x and y can be forgotten for a minute and the idea of a polygon can be forgotten too
first of all. realize that the shaded shape has 4 sides and 4 angles has 360 degrees total in its angles. x + y = 80, therefore the two angles left must equal 280 and must each be 140 degrees. now for the big shape. remember that with each new side, the total amount of degrees in the shape increases by 180. now find a multiple of 140 that is also a multiple of 180. using a calculator and plugging in the various given solutions we can find that the number of sides if 9

actually i typed it the way i figured it out. sorry if you thought i was being pompous.

hunter, that question is definitely not above precal so quit boasting about how you're "only in precal". it's not a hard problem. it's just worded strangely

i got fed up with lag so didn't bother watching the solution to the problem. i couldn't get it but i only thought about it for like 30 seconds.
