An electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 23 feet up. The
leva [86]

The length of the ladder that makes an angle of 75 degrees and lies against the wall of a house that's 23 feet tall is <em>approximately </em>25.88 feet.

The ladder forms a right triangle as it lies against the wall as shown in the image below.

<em><u>Thus:</u></em>

x = length of the ladder (hypothenuse)

Reference angle (\theta) = 75^{\circ}

25 ft = Opposite

Apply SOH:

<em>Thus</em>,

sin(\theta) = \frac{Opposite}{Hypotenuse}

  • Plug in the values

sin(75) = \frac{25}{x}\\\\x = \frac{25}{sin(75)} \\\\\mathbf{x = 25.88}

Therefore, the length of the ladder that makes an angle of 75 degrees and lies against the wall of a house that's 23 feet tall is <em>approximately </em>25.88 feet.
