Triginomotry problem please. (really easy one)

[Rendascus]

The only thing I remember is a2+b2=c2

So just uhm....find the square root of that
and yeah. i don't remember anything else

[Spirit]

the Sq root of the hypotenuse is 4.242 if that helps

[Mr. First Name Basis]

You guys are using trig identities, the hard way.

a^2 + b^2 = c^2

That's for losers.

SOH-CAH-TOA is where it's at.

Oh and for the above post, yes the triangle does have a and b. Each leg corresponds.

He doesn't have the values for a and b though.

The problem with that is he doesn't have a OR b, just c. So that won't work.

I wish I could be more helpful, I was really good at math last year, Almost made a 100 in Algebra II. But our math class is so damn laid back this year I feel like I have forgotten just about everything I used to know. We aren't really pressured into trying and I don't give a shit about math enough to actually take any initiative myself so I just kind of cruise by with a C now.

Useless post is useless... sorry I can't help.

Can you use the trigonometry table with the sin cos and tg values?
If you can it's easy...
All you need to do is sin64 = y/hipotenuse
It is 0,898794 = y/18
y = 0,898794 x 18
y = 16,178292

And to find x you just do cos64 = x/hipotenuse
0,438371 = x/18
x = 0,438371 x 18
x = 7,890678

If you can't use the trigonometry table then I have to think more...

Hope I helped you...

Post above...
To do a cosine law you usually need 2 sides and 1 angle..
But it's not neccessary at all..
It's a triangle with a 90 degrees angle...
