Question

What is length of segment QR? (Show all work)

Answer 1

Answer:

$x=15\ units$

Step-by-step explanation:

we know that

The Midpoint Theorem states that the line segment joining the midpoints of any two sides of a triangle is parallel to the third side and equal to half of the third side

so

In this problem

Applying the Midpoint theorem we have that

$x=\frac{30}{2}=15\ units$
