34 cos (3 0^{\circ})

Use the following trivial identity:

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

cos (3 0^{\circ})

cos (x)

= \frac{3}{2}

= 34 \cdot \frac{3}{2}

Simplify

34 \cdot \frac{3}{2} : 173

34 \cdot \frac{3}{2}

Multiply fractions:

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

= \frac{3 \cdot 34}{2}

Divide the numbers:

\frac{34}{2} = 17

= 173

= 173
