Solution steps

90 sin (6 0^{\circ})

Use the following trivial identity:

sin (6 0^{\circ}) = \frac{3}{2}

sin (6 0^{\circ})

sin (x)

periodicity table with

36 0^{\circ} n

cycle:

= \frac{3}{2}

= 90 \cdot \frac{3}{2}

Simplify

90 \cdot \frac{3}{2} : 453

90 \cdot \frac{3}{2}

Multiply fractions:

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

= \frac{3 \cdot 90}{2}

Divide the numbers:

\frac{90}{2} = 45

= 453

= 453
