Step-by-step explanation:

Answer:

42

Step-by-step explanation:

3/(3+x-6)=5/(5+x)

cross multiply

3(5+x)=5(3+x-6)

15+3x=15+5x-30

15+3x=5x-15

15+15=5x-3x

30=2x

x=15

That means KQ=15 and PK=15-6=9.  Now we have to find PQ, which is the same as JM.  We’ll call that length b.

5/15=6/b

cross multiply

5b=90

b=18

15+9+18=42
