    To get the hypotenuse of the triangle which is AC you need to do the cos function (Make sure your calculator is in Degree mode!) It would look like this: cos40=AC10 The other leg of the triangle (AB) would be the tan function or if you know both BC and AC you could do the Pythagorean Theorem: a2+b2=c2 If you do tangent then your answer would be gotten like this: tan40=AB10
