    The 3-4-5 triangle)
    opposite = 4, adjacent = 3 therefore we use Tan.
    Tan Theta = 4/3
    Theta = 53.13 degrees

    The 24-10-26 triangle)
    opposite = 10, hypotenuse = 26 therefore we use sine
    Sin Theta = 10/24
    Theta = 24.62 degrees

    The 5-4-8 triangle)
    adjacent = 4, hypotenuse = 8 therefore we use cosine
    Cosine Theta = 4/8
    Theta = 60 degrees

    For the last one, I don't know what you want me to solve. Area? Angles? Lengths? And is it a non-right angled triangle? And, is that an 18?

    Note that the opposite and adjacent change, relative to the angle you're looking at.

    Here's a little acronym for ya: SohCahToa.

    Sine = opposite/hypothenuse
    Cosine = adjacent/hypothenuse
    Tangent = opposite/adjacent :)

    Its Hypotenuse, not hypothenus ;)

    Would post my "Kinematics of a particle moving in a straight line or on a plane" homework, but I have no bloody clue of what anything means :>

    Its the movement of a particle. There's 5 kinematics equations for projectile motion, So I guess straight line movement would be even easier xD I do Physics as well so if you post it, I'll be able to go through it step by step for you :)

    Would you mind running me through how to do it so I don't have to ask next time? ^-^;
