c2 = a2 + b2 - 2abcos(theta)

edit: where c is the side opposite theta, and a and b are the other two sides

(A*A) + (B*B) = (C*C)
Then find the square root of (C*C)

Can't be arsed to find the shortkeys, ill stick to a pencil

That's Pythagoras's Theorem (sp?), not what he's looking for

Draw a line from to apex to the base so you have two right angled triangles, then just work out the size for each then add them.
He'll get the answer, but it won't be the right way to do it. Question asks to solve X using the Law of Cosines.

That only applies for right-angle triangles.

Law of Cosines (as taken from my Pre-Calculus notes)

c2 = a2 + b2 - 2ab(cos γ)

*Note: γ is angle directly opposite c side. The formula can be changed to suit the a or b sides as well. Basically, just use the above as an example, where you use c and gamma together, a and alpha, and b and beta. Other than that, you should be able to make it work.

You have a book right? Or better yet, you're connected to the internet right? Look up the law of cosines!

YES!

lol, not to be a dick but come on man... it says right on the problem use law of cosines. Its one equation that gives the answer. If you couldn't remember law of cosines look that up!

I always remembered it ass

      O          A         O
    S   H    C   H    T    A                       

O = Opposite, A = Adjacent, S/C/T = The angle or whatever, so you fill in the 2 you have and follow the triangle rules

Good for you.... but it doesn't help at all in this scenario
