Atree casts a shadow of 24 feet at the same time as a 5-foot tall man casts a shadow of 4feet. find the height of the tree.

30 ft

Step-by-step explanation:

This is a problem of similar triangles.

          <24>

      tree     man

The height of the man is 5 ft.

The shadow of the tree is 24 ft.

The shadow of the man is 4 ft.

We have similar triangles, so the lengths of their sides are proportional.

h/24 = 5/4

Cross multiply.

4h = 24 * 5

Divide both sides by 4.

h = 6 * 5

h = 30

30 ft

i got 86 for this

hope this !

if you need an explanation just ask

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
