a christmas tree is 34 feet tall. it casts a shadow 24 feet long. toms christmas tree is standing beside the tree at rockefeller center and is 5 feet 8 inches tall. how long of a shadow would toms tree cast?
Let x be the length of the shadow cast by Tom's tree. Set up a ratio:
5ft 8in = 5+(8/12)ft = 17/3ft
24/34 = x/(17/3)
