Question

find the missing side of special right triangles. leave answer as radicals in simplest form.

Answer 1

use sine law..

Answer 2

but i need it in radical form?!

Answer 3

\[\sin(60)=\frac{7}{x}\]
\[\frac{\sqrt{3}}{2}=\frac{7}{x}\] solve the ratio for \(x\)

Answer 4

oh you need \(x\) and \(y\) ?

Answer 5

yes please!

Answer 6

i need x and y and in radical form! thanks so much ur so kind;)

Answer 8

sides of a 30 60 90 triangle are always the same ratio

Answer 9

ok this is what you do
the ratios for a 30-60-90 right triangle are \(1:\sqrt{3}:2\) for
short side: long side: hypotenuse

you have long side = 7 so
\[\frac{7}{\sqrt{3}}:7:\frac{14}{\sqrt{3}}\]
