If the denominator is greater than nominator.
5 / 14
if you graph the two points, just count the units and put them in a simplified fraction (rise (up or down) divided by run (side to side))
These are alternate exterior angles
they alternate (or cross) the traversal (the center line)
and they are exterior (they are both outside)
and they are equal
100 = x + 105 subtract 105 from both sides
-105 -105
-5 = x
x = -5
