Answer:

108+x=180

or,x=180-108

x=72

If angle x and angle y are supplementary angles that means that their sum is 180 degrees

angle x + angle y = 180

^^^Plug what you know into the equation given above

angle x = unknown

angle y = 108

x + 108 = 180

x + 108 - 108 = 180 - 108

x = 72

Angle x is 72 degrees

Hope this helped!
