tan 46=250/x,find x

anonymous · Answer

SOH CAH TOA
$$Sin = \frac{Opposite}{Hypotenuse}$$
$$Cos=\frac{Adjacent}{Hypotenuse}$$
$$Tan = \frac{Opposite}{Adjacent}$$

You'll need these in future math classes :)

anonymous · Answer

But Surjithayer is correct. Tan = O/A:
Tan(46) = 250/x
solve for x, put it into a calculator, and you're done!

i'm so confused x=125/230an

anonymous · Answer

I'm not sure what happened there.

$$Tan(46^o) = \frac{250}{x}$$
Tan(46) is just a number. We'll just treat it like one.

Multiply both sides by x:
$$x Tan(46^o) = 250$$
Then divide both sides by Tan(46):
$$x=\frac{250}{Tan(46^o)}$$

anonymous · Answer

x=250 cot 46= 250 cot(90-44)=250 tan 44=?

anonymous · Answer

x=241!

There you go :)

Do you see how to do it? That's the important part.
