Answer:
85 degrees
Step-by-step explanation:
its really easy just make them equal to eachother and then solve
9x + 13 = 11x-3
-11x (subtract because 11x is positive)
-2x +13 = -3
-13 (subtract because 13 is positive)
-2x = -16
divide both sides by -2
x= 8
substitute 8 for the x's and you have your answer
