\frac{7071 2}{40}

Decimal Notation

249.99760 \dots

Solution steps

353.55 sin (4 5^{\circ})

= \frac{7071}{20} sin (4 5^{\circ})

Use the following trivial identity:

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

sin (4 5^{\circ})

sin (x)

= \frac{2}{2}

= \frac{7071}{20} \cdot \frac{2}{2}

Simplify

\frac{7071}{20} \cdot \frac{2}{2} : \frac{7071 2}{40}

\frac{7071}{20} \cdot \frac{2}{2}

Multiply fractions:

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

= \frac{7071 2}{20 \cdot 2}

Multiply the numbers:

20 \cdot 2 = 40

= \frac{7071 2}{40}

= \frac{7071 2}{40}
