Please Help!!!

A pair of parallel lines is cut by a transversal:

A pair of parallel lines is cut by a transversal. The interior angle made on the left by the intersection of the upper parallel line and the transversal is divided into 2 parts by a slanting line. One part of this angle is labeled as x, and the other part is labeled as 30 degrees. The interior angle made on the right by the intersection of the lower parallel line and the transversal is labeled as 75 degrees.

What is the measure of angle x?

10 degrees
15 degrees
45 degrees
60 degrees

Answer 1

15 degree or watt quite not sure

Answer 2

9514 1404 393

Answer:

45 degrees

Explanation:

Alternate interior angles where a transversal crosses parallel lines are congruent:

x + 30 = 75

x = 45 . . . . . . degrees
