What is the measure of angle x in the figure below?

Answer:
x=45
Step-by-step explanation:
rectangles=360
90+90+135+x=360
315+x=360
x=45
This is a right trapezoid.
x+135⁰=180⁰
x=180⁰-135⁰=45⁰
However this value is not consistent with the numerical values of the sides. This is because 10-7=3m and height is 5m. If x=45⁰, then we would have 3m=5m....
The problem has serious flaws..
