Answer:
E. 7.8
Explanation:
We have been given an image of a triangle and we are asked to find the distance from point N to line LM.
We can see that NO is the altitude for our given triangle, so the distance from point N to line LM will be equal to length of segment NO.
We can see from our given attachment that length of segment NO is 7.8 units, therefore, option E is the correct choice.
