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.

How do you solve this?

Use PEMDAS
figure out everything inside the parentheses first, you still have to do PEMDAS inside of the parentheses also.
