Answer:
z = 67
x = 17
Step-by-step explanation:
The reason for this is because to solve for x, you have to set up the equation:
(6x+11) + (9x - 86) = 180 since those two are supplementary which means they equal 180 degrees. You solve for x which is 17. Then you do 9 (17) - 86 because you plug in 17 to the x. Solve for z which is 67. There you go. Let me know if this doesnt make sense. Good luck!
