2.8*cos(60)

Solution

2.8 \cdot cos (6 0^{\circ})

Solution

\frac{7}{5}

+1

Solution steps

2.8 cos (6 0^{\circ})

= \frac{14}{5} cos (6 0^{\circ})

Use the following trivial identity:

cos (6 0^{\circ}) = \frac{1}{2}

= \frac{14}{5} \cdot \frac{1}{2}

Simplify

\frac{14}{5} \cdot \frac{1}{2} : \frac{7}{5}

= \frac{7}{5}
