    I’m assuming it’s a right triangle and you’re finding the hypotenuse. C is always the hypotenuse.

    a^2+b^2=c^2
    8^2+7^2=c^2
    64+49=c^2
    113=c^2
    c=sqrt113

    If it’s another side just sub it in.
    8 is largest so it’s c.
    using the same formula
    64=49+b^2
    64-49=b^2
    15=b^2
    b=sqrt15
