Question

Please answer this!! (look at picture)

The alien is 5 feet tall and his shadow is 8 feet long. At the same time of day a tree's shadow is 32 feet long. Use triangle similarity to find the height of the tree.

Answer 1

20 feet (By the way can I have brain list)

Explanation:

Lance the alien is 5 feet tall. His shadow is 8 feet long. At the same time of day, a tree's shadow is 32 feet long. What is the height of the tree?

We solve this using proportion of

Height/ Shadow

= 5/8 = x/32

Cross Multiply

8x = 5 × 32

x = 5 × 32/8

x = 20 feet

The height of the tree is 20 feet

Answer 2

Height of the tree = 20 ft

Explanation:

A basic equation can be formed to solve this:

`(5)/(8) = (x)/(32)`

`x = (5 * 32)/(8)`

`x = 20 ft`

Therefore, the height of the tree is 20 ft.
