Answer:

23.590 feet

Explanation:

The mnemonic SOH CAH TOA reminds you of the relationship between trig functions and sides of a right triangle:

Tan = Opposite/Adjacent

Here, that means ...

tan(65°) = height/(11 ft)

Multiplying by 11 ft, we get ...

height = (11 ft)tan(65°) ≈ 23.5896 ft

height ≈ 23.590 ft
