Explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relations between trig functions and sides of a right triangle.
Here, we're given the side opposite the angle, and we want to find the side adjacent to the angle. The relevant trig function is ...
Tan = Opposite/Adjacent
Filling in the given values and solving for the adjacent side, we have ...
tan(35°) = 3/?
? = 3/tan(35°) . . . . . . multiply by ?/tan(35°)
? ≈ 4.28
AC is about 4.28 units long.
