We know that WZ is a line, and all lines measure 180 degrees.
Therefore, Angle PWX + Angle PYX + Angle PYZ = 180 degrees. Plug in what we know:
Simplify:
Subtract 110 to both sides:
So angle PYZ is 70 degrees.
Angle ZX is equal to Angle PYX + PYZ.
Therefore, Angle PWX + Angle PYX + Angle PYZ = 180 degrees. Plug in what we know:
Simplify:
Subtract 110 to both sides:
So angle PYZ is 70 degrees.
Angle ZX is equal to Angle PYX + PYZ.
