Solution

62

+1

Decimal Notation

8.48528 \dots

Solution steps

sin (4 5^{\circ}) \cdot 12

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}

= \frac{2}{2} \cdot 12

Simplify

\frac{2}{2} \cdot 12 : 62

\frac{2}{2} \cdot 12

Multiply fractions:

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

= \frac{2 \cdot 12}{2}

Divide the numbers:

\frac{12}{2} = 6

= 62

= 62
