By the Alternate Interior Angles Theorem, the measure of angle K is 50°. the correct option is B. mK = 50°
Calculating values of angles
From the question, we are to determine the measure of angle K.
From the given information,
Angles L and K are alternate interior angles
By The Alternate Interior Angles Theorem which states that when two parallel lines are cut by a transversal, the resulting alternate interior angles are congruent.
Since the measure of angle L is 50°
The measure of angle K is also 50°
Hence, by the Alternate Interior Angles Theorem, the measure of angle K is 50°. the correct option is B. mK = 50
