arlik [135]

Answer:

height of the tree is 30 feet

Step-by-step explanation:

a tree casts a shadow 42 feet long . at 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

Let x be the height of the tree

shadow of a 42 feet tree is x feet long

Make a proportion

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

cross multiply

$7x=(42)(5)$

$7x=210$

divide by 7 on both sides

x=30

So height of the tree is 30 feet
