Answer 2

Answer:

Step-by-step explanation:

setup a proportion

                               Big Triangle             Small Triangle

corresponding              15                              3

corresponding               x                               6

so you are trying to solve 15/x=3/6

cross multiply 6(15)=3(x)

last step divide both sides by 3 giving x=30 ft
