Question

What is the value of x

Answer 1

X=149

Explanation:

Lines m and n are parallel. You know this because the 2 marks on both lines mean that they are the same and parallel.

Answer 2

x = 149

Explanation:

Lines m and n are parallel lines as shown by the double arrows on each line.

The angles marked x and 149 deg are corresponding angles of parallel lines cut by a transversal.

Postulate:

If parallel lines are cut by a transversal, then corresponding angles are congruent.

According to the postulate above, since the angles marked 149 and x are corresponding angles, they are congruent.

x = 149
