Solution steps

22 sin (4 5^{\circ})

Use the following trivial identity:

sin (4 5^{\circ}) = \frac{2}{2}

sin (4 5^{\circ})

sin (x)

periodicity table with

36 0^{\circ} n

cycle:

= \frac{2}{2}

= 22 \cdot \frac{2}{2}

Simplify

22 \cdot \frac{2}{2} : 112

22 \cdot \frac{2}{2}

Multiply fractions:

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

= \frac{2 \cdot 22}{2}

Divide the numbers:

\frac{22}{2} = 11

= 112

= 112
