A pole 6m high has a shadow 10 m long when the shadow of a nearby building is 220 m long. How tall is the building? Which ratio is equal to the ratio of the height of the building to its shadow?
I have been working on this for 30 minutes know and I cant get the answer...>.<

height of pole/length of pole's shadow = height of building/length of building's shadow
let x = height of building
height of pole = 6
length of pole's shadow = 10
length of building's shadow = 220
6/10 = x/220
cross multiply and solve for x
oh, I guess they're looking for the ratio, so after you find the height of the building, you would divide
height of building/length of building's shadow
