In the figure, mZ1 = (x + 11)°, mZ2 = (3x + 7), and mZ4 = (5x + 6)°. Write an expression for mZ3. Then find mZ3.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
