Letters w, x, y, and z are angle measures.

lines r and s are intersected by line m. at the intersection of lines m and r, clockwise from the top, the angles are w, x, blank, blank. at the intersection of lines m and x, clockwise from the top, the angles are: 92 degrees, y, z, blank.

which should equal 92° to prove that r ∥ s?

x
y
z
