The measure of angle 1 would be (3x+2) and the measure of angle 2 would be (5x+10). There is no way to determine the exact degrees of these angles because not enough information is given.
The slope intercept form y=2x^2-x-13. Hope this helps :)
The vertex would be (-2,4)
8x7x6 = 336. There are 8 possible options for slot 1, then 7 for 2, and 6 for the last slot.
Add it together. You find area with base times height!!!
