Answer:

x=6

Step-by-step explanation:

In a rectangle, all angles should be 90 degrees so, you need to solve the equation in the rectangle to 90 degrees. To do this, you first subtract 12 from 90 to get 78 then proceed to divide that by thirteen to isolate the x. Doing all of this should leave you with the answer x=6.
