Answer: x=73 y=73 z=107
Step-by-step explanation:
The angel of x is 73° because opposite angles are always the same.
The angle of y is also 73° because it is on a parallel line so angles on a parallel line would be the same.
Then the angle of z is 107° because the other side of z would be 73° so you need to deduct this from 180° (because a straight line always adds up to 180°).
