A 6 ft pole casts a shadow of 8ft long while a nearby flagpole casts a shadow of 56 ftlong. What is the height of the flagpole?

Cross multiply and solve for x.
6/8 = x/56

the ratio is 6/8 (height actual to shadow)
Flagpole height / 56 = 6/8
flagpole height / 56= 3/4
so, the flagpole height is 56*3 / 4 = 42
