Solution steps

6 sin (12 0^{\circ})

Use the following trivial identity:

sin (12 0^{\circ}) = \frac{3}{2}

sin (12 0^{\circ})

sin (x)

= \frac{3}{2}

= 6 \cdot \frac{3}{2}

Simplify

6 \cdot \frac{3}{2} : 33

6 \cdot \frac{3}{2}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{3 \cdot 6}{2}

Divide the numbers:

\frac{6}{2} = 3

= 33

= 33
