In the figure below, the segment is parallel to one side of the triangle. Which of the following is not a true statement? 12/x = 10/15 12/x = y/20 10/25 = y/20

In the figure, you are given a triangle with a line at the center of having measures of 12 and x on one side, 10 and 15 on the other side and y and 20 at the bottom side. To get the values of each variable, you have to correctly assign their proportions.

First equation:

(12+x) / 12 = 25/10

12+x = 12 (25/10)

12+x = 30

x = 30 - 12

x = 18

y/20 = 10/25

y = 20 (10/25)

y = 8
