I hope you can see that but it says that all triangles are similar then asks for the altitude given 2 hypos. 2 hypos/side are 20 and 15 respectively. Can't figure this out, found the side JL = 25 but still can't figure out how to calculate the altitude/KM
The triangles are similar, because 3 pairs of correspondending sides are in the same ratio.
So here we have: 25:20:15 = 5:4:3.
Now you have to find: 20:JM:KM.
