A video game has three difficulty levels: easy, medium, and expert. The game's scoring works in such a way that a player has to

score a fixed number of points to advance to the next level, and then the scoring starts over. The total score needed to clear all three difficulty levels is 7,500. Two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. Twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. If x, y, and z represent the easy, medium, and expert levels, respectively, and A is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, A-1, and the solution matrix, X, of the system of equations.

the area A of a sector circle is given by A= ... idk how to write that so look at the image please lol
Pavel [41]
A=πr^2s/360  multiply both sides by 360

360A=sπr^2  divide both sides by πr^2

s=360A/(πr^2)
