9x-28=5x-8
9x=5x+20
4x=20
x=5
(9x-28)+(5x-8)=
(17)+(17)=34
YMX= 34 degrees

Answer:

x = 5

Step-by-step explanation:

9x - 28 = 5x - 8 (because Y and X are equal, and XZ and YZ are equal)

add 8 to both sides

9x - 20 = 5x

subtract 9x from both sides

-20 = -4x

divide 4x from both sides

5 = x

x = 5
