Find m/angle xyz in the figure below.

To answer this question you would start by finding the angle measure of either XYW or ZYV. To do this you would set up the equation 3x+23=7x-37. Start by adding 37 to both sides, getting a new equation of 3x+60=7x. The subtract 3x from both sides, getting 60=4x. Finally, divide both sides by 4, getting x=15. You would then plug 15 in for x in either (3x+23) or (7x-37). I'm using (3x+23). 3(15)+23, multiply 3 by 15, getting 45+23, then add 45 and 23, getting 68 as your angle measure. Finally, subtract 68 from 180 to get your answer, 112.
