All angles in any quadrilaterals(any shape with 4 sides) add up to 360. There are two right angles in the trapezoid which represents 90 degrees. We are also given the angle 52 degrees. To find x, we need to add all the values together and subtract from 360. To do this the equation should look like this: 90 + 90 + 52 + x =360. This simplifies to 232 + x = 360. Then we subtract 232 from both sides to find x. x = 128.
Step-by-step explanation: to find what X equals for each equation you have to get X alone to get X alone in the first option you have to do +3 to both sides of the equal sign which leaves you with x=3 which you then do for the rest of the options an select all the one left with x=3.
