5x - 1 = 15x - 101
101 - 1 = 15x - 5x
100 = 10x
100/10 = x
x = 10
How this has been solved is by bringing the equations with (x) to one side and solving them and solving the other numbers on the other side..
Angle 1 is 107 degree, and the other one is 73 degrees (180-107=73)
Answer:The line that is congruent to angle 4 is angle 1
