Answer 1

so we know that 43 and y are congruent so y = 43.

we also know that y + x has to equal 180

so

180 - 43 = 137

so x is 137. We also know that z and x are congruent, so therefore z is 137.

Explanation:

Answer 2

Z + 43 = a straight line which needs to equal 180 degrees.

Z = 180 - 43 = 137

answer: z = 137 degrees
