Question 942186: parallel lines and proportional parts of triangles
There is a triangle with a line that divides the triangle and is parallel to the bottom of the triangle. The left side of the triangle has measurements of 6 and 8, or 14 in all. The right side of the triangle is divided into 15 and x. What is the value of x? please help me, thank you.

If x is the corresponding partner to 8, then
6%2F14=15%2F%2815%2Bx%29
90%2B6x=210
6x=120
x=20
If x is the corresponding partner to 6, then,
8%2F14=15%2F%2815%2Bx%29
8%2815%2Bx%29=14%2A15
120%2B8x=210
8x=90
x=90%2F8
x=45%2F4
