Find the values of x, y, and z in the triangle to the right.
A triangle has angles labeled as follows: lower left, x degrees; top, y degrees; lower right, z degrees. A ray extends the left side of the triangle and the angles labeled y degrees and (2 x plus 2) degrees form a straight angle. Another ray extends the bottom side of the triangle and the angles labeled z degrees and (2 x minus 2) degrees form a straight angle.
x degrees
y degrees
z degrees
left parenthesis 2 x plus 2 right parenthesis degrees
left parenthesis 2 x minus 2 right parenthesis degrees
