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 t
he 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 25 degrees. The interior angle made on the right by the intersection of the lower parallel line and the transversal is labeled as 60 degrees. What is the measure of angle x?
SInce you have parallel lines cut by a transversal, alternate interior angle are congruent. The 60 degree angle and the (x + 25) degree angle are congruent. Therefore, 60 - 25 = 35 x = 35
