Solution

1.2 cos (3 0^{\circ})

Solution

\frac{3 3}{5}

+1

Solution steps

1.2 cos (3 0^{\circ})

= \frac{6}{5} cos (3 0^{\circ})

Use the following trivial identity:

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

= \frac{6}{5} \cdot \frac{3}{2}

Simplify

\frac{6}{5} \cdot \frac{3}{2} : \frac{3 3}{5}

= \frac{3 3}{5}
