Question

Segment LM is the midsegment of trapezoid ABCD, AB= 38, and DC=78. what is LM?

Answer 1

The length of the midsegment of trapezoid is half the sum of the lengths of the two parallel sides. In the figure above:
therefore
\[LM=\frac{ AB+ DC }{ 2 }\]
\[LM= \frac{ 38+78 }{ 2 }\]
\[LM= 58\]

Hope that helps :)
