Find the values of y and x. Use the and tool to show and explain your work.

y = 68 x = 20 The unlabeled angle must measure 44 degrees to complete the 180 degrees of the obtuse triangle on the left. Since the 2 y's and 44 degree angle form a linear pair. Each y must be 68 degrees. So, x must be 20 to add up to 180 degrees in the triangle on the right.
