Answer:
LM = 5
Explanation:
Theorem:
In a triangle, the segment that connects the midpoints of two sides is parallel to and half the length of the third side.
LM connects points L and M which are midpoints of two sides of the triangle.
Therefore, segment LM is parallel to segment RP, and segment LM is half the length of segment RP.
LM = (1/2)(RP)
LM = 1/2 × 10
LM = 5
