Answer:
C
Step-by-step explanation:
Angle 6 and 45 degrees are equal. Corresponding angles along a transversal are equal; thus angle 2 is equal to 45 degrees as well. Since 5x+35 and 45 degrees are along the same line, they must add up to 180 degrees. 180-45 = 135; 5x+35 = 135. 5x = 100; x = 100/5 = 20
