ABCD is a parallelogram. Use deductive reasoning to find the measure of x and y. Here is an example of how to type out a deductive argument: a + 70 degrees = 180 degrees (angles on a line) a = 110 degrees x + 110 degrees + 35 degrees = 180 degrees (angle sum of triangle) x + 145 degrees = 180 degrees Therefore, x = 35 degrees.
