Answer: Ok I will help you. It is 5.34 (The second choice).
Step-by-step explanation: The hypotenuse isn't known, so we don't have to care about it. It is a right triangle. We are looking for opposite over adjacent, which is trigonometry.
Soh = Opposite / Hypotenuse (sin)
Cah = Adjacent / Hypotenuse (cos)
Toa = Opposite / Adjacent (tan)
x/12=tan24
12*tan24=x
