Answer to Question #133131 in Geometry for Toni Serra

Question

K is between J and M. L is between K and M. M is between K and N. If Jn=30, KM=8, and Jk=kL=lm, what is MJ?

Answer 1

$KL+LM=KM$

If $KL=LM$ and $KM=8$, then

$2*KL=8$

$KL=8:2$

$KL=4$

If $KL=JK=LM$, then $KL=JK=LM=4$

So, $MJ=JK+KL+LM$

$MJ=4+4+4$

$MJ=12$

And this task has surplus statement $JN=30$, that was unnecessary to solve.

Solution: $MJ=12$
