(Round the answer to the nearest thousandth if necessary)

Answer 1

0.225

Explanation:

The mnemonic SOH CAH TOA reminds you of the definition of the tangent of an angle.

... Tan = Opposite/Adjacent

The side opposite angle C is AB. The side adjacent to angle C is BC. Then ...

... tan(C) = AB/BC = 18/80 = 0.225
