Answer 3

@breannemariie

If a line is parallel to one side of a triangle and intersects the other two sides of the triangle, then it divides those lines proportionally.

So.

(15 - y) / y = 20 / 10

Answer 4

Cross Multiply.

20 y = 10(15 - y)

Solve for y. It is one of the options.

Answer 5

so, 5? @Directrix :)

Answer 6

Yes.

Answer 7

20y=10(15-y)
20y=150-10y
20y+10y=150
30y=150
y=150/30
y=5
