Answer 2

Answer:

  30.9 ft

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

  Cos = Adjacent/Hypotenuse

In this scenario, the side adjacent to the 75° angle is the 8 ft distance from the building. The hypotenuse of the triangle is the ladder. So, we have ...

  cos(75°) = (8 ft)/(ladder length)

  ladder length = (8 ft)/cos(75°) ≈ 30.9 ft

The ladder is about 30.9 feet long.
