I need help with geometry

Ede4ka [16]

Answer:

corresponding angles

the angles are equal

equation: 9x+8 = 4x+18

x=2

angle measurements: 26⁰

Step-by-step explanation:

solve your equation

9x+8 = 4x+18

subtract 4x from each side

5x + 8 = 18

subtract 8 from each side

5x = 10

divide by 5

x = 2

insert x=2 into original equations to make sure you get the same answer.

9(2) + 8 = 26

4(2) + 18 = 26
