Is it possible to have a polygon whose sum of the interior angles is 500

The answer is No. the Sum of interior angles of an n-gon is 180(n-2), which must be a multiple of 180 for integer n. 500 is not a multiple of 180.

d. all of the above

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
