Answer: x = 64
=============================================================
Explanation:
Combining all of the angles shown in the diagram leads to 360 degrees. This is because there are 360 degrees in a full rotation.
Let's add up the angles shown and set the sum equal to 360. Keep in mind that the square angle marker represents 90 degrees (aka a right angle).
180+26+x+90 = 180
x+296 = 360
x = 360-296
x = 64
