Question

What is the distance between points M and N?

Answer 1

Answer:

$MN=9.8\ m$

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The Triangle Midpoint Theorem states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side.

In this problem

Point N is the midpoint segment JL and the point M is the midpoint segment KL

so

The segment MN is joining two sides of a triangle at the midpoints of those sides

therefore

MN is parallel to side JK and is half the length of JK

$MN=\frac{1}{2}JK$

we have

$JK=19.6\ m$

substitute

$MN=\frac{1}{2}(19.6)=9.8\ m$
