    cos(A) = adjacent/hypotenuse which side is the side adjacent to A? which is the hypotenuse?

    that's the hypotenuse, try again

    nope, try again... adjacent means the side next to the angle, NOT including the hypotenuse

    see how "opposite" is on the opposite side of the triangle? see how "adjacent" is next to A but NOT the hypotenuse? see how the hypotenuse is the longest side? so, if cos(A) = adjacent/hypotenus, what is cos(A)?

    no, keep trying... cos(A) = adjacent/hypotenuse what is the adjacent side?

    AB is opposite to C and AC is adjacent to C, right? we know that tan(C) = opposite/adjacent, so tan(C) = 4/9 solve for C
