x = 14
Explanation:
height = x
base 1 = 98
base 2 = 2
Using altitude formula in geometric mean:
base 1/height = height/base 2
98/x = x/2

The first one is none of above, it is vertical opposite angles.
the second to the left is also none of above, since the 2 lines are not parallel to each other.
the third one in the right is corresponding
the fourth one is alternative exterior
the last one is none of above because again the lines aren't parallel
