Answer:

<u>AC</u><u> </u><u>i</u><u>s</u><u> </u><u>6</u><u>.</u><u>5</u><u> </u><u>cm</u>

Step-by-step explanation:

From trigonometric ratios:

\sin( \theta)  =  \frac{opposite}{hypotenuse}  \\

opposite » 3 cm

hypotenuse » AC

angle » 28°

\sin(28 \degree)  =  \frac{3}{AC}  \\  \\ AC =  \frac{3}{ \sin(28 \degree) }  \\  \\ AC =  \frac{3}{0.46}  \\  \\ AC = 6.5 \: cm
