Answer:

28

Step-by-step explanation:

Since the triangle is a right triangle, we can use SOH CAH TOA to find ?. 10 is OPPOSITE to ? and 21 is HYPOTENUSE to ?, so we can use SIN to find ?.


SIN(?) = 10/21

? = ARCSIN(10/21)

? = 28.437

What is 1/7 divided by 252 ?
miskamm [114]

Answer:

In decimal form: 0.00056689342 (If wanted to round to nearest thousandth, 0.001)

In fraction form: \frac{1}{1764} or \frac{28344671}{50000000000}

Step-by-step explanation:

\frac{1}{7}\div \:252=\frac{1}{1764}

\mathrm{Convert\:element\:to\:fraction}:\quad \:252=\frac{252}{1}\\=\frac{1}{7}\div \frac{252}{1}

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}\\=\frac{1}{7}\times \frac{1}{252}

\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}\\=\frac{1\times \:1}{7\times \:252}

\mathrm{Multiply\:the\:numbers:}\:1\times \:1=1\\=\frac{1}{7\times \:252}

\mathrm{Multiply\:the\:numbers:}\:7\times \:252=1764\\=\frac{1}{1764}

Hopes this helps you!

Have a wonderful night!

Happy Monday!
