Have a couple questions:
1) what is the solution of the proportion?
2) the polygons are similar. The smaller one is AD=12,DC=3, the bigger one JM=40,ML=x
Cross multiply and solve for x.
7m + 280
m = 40
Thanks for the help on one problem
I was looking for how to do proportions, i had forgot.
You're welcome. Sorry I can't help you with the second problem.
