It takes 45 seconds. the easiest way to do these is to use a graphic calculator and replace the variables with x and y, for example, this equation would become -5x^2+30x, and if you don't have access to a graphing calculator, you can always use desmos online.
The answer would be 137 degrees because of supplementary angles of x and 43 degrees. Then the angle opposite of x (z) is the same as x.
