A wire that is 22 feet long connects the top of a pole to the ground. The wire is attached to the ground at a point that is 10 feet from the base of the pole.

What is the height of the pole? Round to the nearest hundredth.
12.00 feet
19.60 feet
24.17 feet
38.40 feet

Respuesta :

Solution:

Length of wire = 22 feet =AB

Distance between the point where wire is attached to the ground from the point on the ground where pole is fixed= 10 feet=OB

In Right Δ O A B

By Using pythagoras theorem

O A²  + OB² = AB²

O A² +10²= 22²

O A²= 484 - 100

O A²= 384

O A= √384= 19.60 (Approximately)

So, the height of pole to nearest hundredth = 19.60 feet

The height of the pole is 19.60 ft

The situation forms a right angle triangle.

Right angle triangle

Right angle triangle have one of its sides as 90 degree.

The length of the wire is the hypotenuse of the triangle formed.

The distance of the wire attached to the ground to the base of the pole is the adjacent side of the triangle.

The height of the pole can be found using Pythagoras theorem.

c² = a² + b²

22² - 10² = b²

b² = 484 - 100

b = √384

b = 19.5959179423

b = 19.60 ft
