SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Draw the given image

STEP 2: Explain the alternate interior angles

Alternate interior angles are the angles formed when a transversal intersects two coplanar lines. They lie on the inner side of the parallel lines but on the opposite sides of the transversal. The transversal crosses through the two lines which are Coplanar at separate points.

This can be seen with the image below:

Therefore, from the explanation above, PQR will be equal to 40 degrees as seen in the image in step 1.

Hence,

Angle PQR measures 40°.
