If a tree cast a shadow that is 42 feet long and a man, whose height is 6 feet, cast a shadow that is 5 feet long. How tall is the tree?

height of the tree is 30 feet

Step-by-step explanation:

the same time, a person 5 feet tall casts a shadow 7 feet long.

shadow of a 5 feet tall person is 7 feet long

shadow of a 42 feet tree is x feet long

\frac{x}{42} =\frac{5}{7}

42

x
