Answer: 896
Step-by-step explanation:
Let's use a rule of three here.

Solve for x;


All of the surfaces are rectangular
So, you already know that angle CBD is 68 degrees, and the complementary angle to angle CBD is angle CBA. These angles together make 180 degrees because segment DBA is a straight line consisting of angles CBD and CBA. 180-68(the angle you already know) is 112 degrees for angle CBA. Then you repeat this process to find the other angles
If you imagine it like the picture below, you could use the pythagorean theorem to solve for x
