Answer: root 70

Explanation:

starting info:

KL = 2NM

KM = 20

NO = 7


Using the fact the ratio of similar sides must be equal:

KL/NO = KM/NM

Therefore sub in values…

KL/7 = 20/NM

As KL = 2NM

2NM/7 = 20/NM

Rearrange:

2(NM)^2 = 140

(NM)^2 = 70

NM = root(70)

(Obviously take positive as can’t have negative length)
