Question

A shadow 9 meters long is cast by a sailboat mast that is 12 meters tall. If a nearby maple tree is 16 meters tall, then how long will the maple tree's shadow be?

Answer 1

16/12 = x/9 = 4/3

x/9 = 4/3

x/3 = 4

x = 12 = maple trees shadow

the shadow is 3/4 of the actual height

3/4 of 16 = (3/4)(16) = 12
