Question

Who know how to do this??

Answer 1

find what the whole line is equal to then take 6.5 and subtract it from the whole thing

Answer 2

Explanation:

With some research I found that the medians (QK, RJ, and SI) are broken into 2:1 ratios.

So what this means is that QD is twice as long as DK.

QD = 2DK

QD = 2 * 6.5

QD = 13
