Sagot :

Answer:

28.42 feet

Step-by-step explanation:

Given

  • Height of tree = 18 feet
  • Length of shadow = 22 feet

To Find

  • Distance b/w top of tree and end of shadow

Solving

  • This resembles a right triangle
  • ⇒ We can use Pythagorean Theorem!
  • ⇒ 18² + 22² = L²
  • ⇒ L² = 324 + 484
  • ⇒ L² = 808
  • ⇒ L = 2√202
  • ⇒ L = 2 x 14.21
  • ⇒ L = 28.42 feet

Answer:

28.4 feet

Step-by-step explanation:

The question can be solved by using Pythagoras Theorem.

Given:-

Height of tree :- 18 feet (Perpendicular)

length of shadow :- 22 feet (Base)

To find:-

Distance of shadow from the end to the top of the tree

Solution:-

We know the Pythagoras theorem,

Which is , H² = P² + B²

So putting the given value , we get

H² = 18²+22²

H² = 324 + 484

H = √ 808 feet

H = 28.4 feet
