$\approx 2.69 2 decimal places$ $≈2.69" 2 decimal places"$

Explanation:

The first step is to $cross-multiply$ $color(blue)"cross-multiply"$

$\Rightarrow c \times {sin 75}^{\circ} = 3 \times {sin 60}^{\circ}$ $rArrcxxsin75^@=3xxsin60^@$

To solve for c, divide both sides by ${sin 75}^{\circ}$ $sin75^@$

$(c cancel(sin75^@))/cancel(sin75^@)=(3sin60^@)/sin75^@$

$rArrc=(3sin60^@)/sin75^@$

$=2.69" to 2 decimal places"$
