Two parallel lines are crossed by a transversal.

Horizontal and parallel lines y and z are cut by transversal x. At the intersection of lines y and x, the bottom right angle is 115 degrees. At the intersection of lines z and x, the uppercase left angle is (3 x + 4) degrees.
What is the value of x?

x = 21
x = 28
x = 35
x = 37

The given angles are alternate interior angles (they lie on opposite sides of the transversal and between the parallel lines), so they are equal:
3x + 4 = 115
3x = 111
x = 37.

Answer: x = 37.
