Expert Solution
Step 1

 

To solve for x :

There are two  parallel lines in the given figure.

A line intersects  these two parallel lines at two distinct points. Hence that line will be a transversal line.

If two parallel lines are cut by a transversal then the corresponding angles are equal.

Hence the angle opposite to (9x + 7)0 is 1150

Since (9x + 7)0 and 1150 are vertically opposite angles. They are equal.
