In triangle rsw, line segment rw is a median and is equal to 27 cm. what is the length of rx?

13.5cm
9cm
27cm
18cm

LAST OPTION.

Step-by-step explanation:

By definition the line segment that goes from a vertex of the triangle to the midpoint of the oposite side, is called "Median of a triangle".

The medians of a triangle intersect at point called "The centroid of the triangle" and this divides each median in a ratio .

In this case, you can notice that the Centroid of the given triangle is the point "X".

Based on the explained before, we can write the following porportion:

Solving for "XW":

Since the lenght of "RX" is 27 centimeters, you know that;

Substituting into and solving for "RX", we get that its lenght is:
