In a parallelogram, the consecutive angles are supplementary (add up to 180 degrees). x can represent the first angle, and 4x can represent the second angle. With this information you can create the equation x + 4x = 180 and solve.
5x = 180
x = 36
So the measure of the first angle is 36 degrees, and the one that is 4 times larger is 144 degrees.
