Below are two parallel lines with a third line intersecting them. If you can’t see it the number is 81

x° = 81°

Step-by-step explanation:

From the diagram, we have;

Two parallel lines crossed by a common transversal

Therefore, the corresponding angle formed by the transversal and each of the parallel lines are equal

The given angle = 81°

The alternate exterior angle to the given angle = x°

When two parallel lines are crossed by a common transversal, the alternate exterior angles are equal

∴ x° = 81°.
