take 64*2 and 90*2 and add those together to get 308. Subtract that from 360 to get the total value of x plus the value of the angle across from it. these two angles will be equal so divide them by two to get your answer.
Step-by-step explanation: It is a 90 degree angle. 64 is already given, so you can subtract 64 from 90 to get the remaining degrees, which is x hope that made sense lol
