Answer:129
Explanation:
Because of the rule of alternate exterior angles the angle to the right of angle X would also be 51 and since we know a straight line is 180 degrees we will subtract the angle we know from 180 and you get 129 as your answer.
Answer:
129
180-51= 129
129 is corresponding with x
and corresponding angles are equal
so 129 is the answer
