Question

Work out the size of angle : x

Answer 1

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 2

129

Explanation:

180-51= 129

129 is corresponding with x
