One side of a parallelogram is AB¯¯¯¯¯ . The height of the parallelogram is 3 units. The parallelogram has no right angles.

Draw the parallelogram using the Polygon tool.

Each segment on the grid represents 1 unit.

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
