Two adjacent angles of a parallelogram always add up to 180. This means that measure W and measure X need to add up to 180:

m<W + m<X = 180

Because measure X is three times the measure of W, we can substitute out measure X for 3 times the measure of W, which will be your answer:

m<W + 3(m<W) = 180
