Question

su is a midsegment of δrtv.
if su = 19, what is rv?

rv = \boxed{}

Explanation:

Step1: Recall the midsegment theorem

The midsegment of a triangle is parallel to the third side and half its length. So, \( SU=\frac{1}{2}RV \).

Step2: Solve for \( RV \)

Given \( SU = 19 \), substitute into the formula \( RV=2\times SU \). Then \( RV = 2\times19 \).

Answer:

\( 38 \)
