A 23 foot long piece of wood is leaning against the wall of a house. If the angle of elevation at the base of the wood to the wall is 75 degrees , how far is the wood from the base of the wall?

22.22 feet

Step-by-step explanation:

The piece of wood forms the shape of a right angled triangle with the wall of the house and the floor.

The piece of wood is 23 feet long and it is the hypotenuse.

The angle of elevation of the wood is 75° and we are to find the length of the wood to the base of the wall. Let that be y.

Using trigonometric function SOHCAHTOA:

sin(75) = x/23

=> x = 23 * sin(75)

x = 22.22 feet

The wood is 22.22 feet far from the base of the wall.

if you explain the the question more correctly i might be able to answer this better
