Answer:

Short answer: D) 15

Explanation:

Parallel lines in this kind of triangle are always in a strict ratio of small to large or large to small based on how you look at it.

So we have 4cm to 6cm, which is 2:3 ratio. We know the smaller side, but want the larger side, so we can set up 2/3 = 10/?

the ? is 15.
