There are two equations to be solved here. The first one we assign variables to the home runs Peter hits, P, and Alice hits, A. P=2*(A-6) The second equation is the sum of both players home runs.P + A = 18Solving for P yieldsP=18-A We substitute the solution for P into the first equation and solve for A.(18-A) = 2*(A-6)18 - A = 2A - 123A = 30A = 10 Now that A is known, we can plug it into either equations for P to find how many home runs Peter hitsP=18 - (10) = 8orP=2((10)-4) = 8
The interior angle plus the exterior angle totals to 180 so you would take 180 and subtract 157.5 and get 22.5 next you would take 360 for the total of degrees that he external angles totals up to. so 360 divided by 22.5 equals the number of sides you shape has and that would be 16 sides.
