    Sin=oposite side/hyptoonuse
    Cos=adjacent side/hypotonuse
    Tan=oposite side/hypotonuse

    oposite side is the side oposite the angle
    adjacent side is the side touching the angle that isn't the hypotonuse
    hypotonuse is longest side





    1.
    first solve for hypotonuse using a²+b²=c²
    hypotonuse=13
    sinA=12/13
    cosA=5/13
    tanA=12/5
    sinB=5/13
    cosB=12/13
    toa=5/12


    2. the missing side is 8
    sinD=15/17
    cosD=5/17
    tanD=15/5=3
    sinE=5/17
    cosE=15/17
    tanE=5/15=1/3


    3. missing side is 25
    you should be able to do this
    sinG=7/25
    do the rest


    4.
    missing side is 6
    sinJ=6/10=3/5
    do the rest
