    Step-by-step explanation:

    I will assume this is a right triangle with the information given

    a^2+b^2 = c^2 is the Pythagorean theorem

    18^2 + b^2 = 30^2

    Subtract 18^2 from each side

    18^2 - 18^2 + b^2 = 30^2 - 18^2

    b^2 = 900 - 324

    b^2 = 576

    Take the square root of each side

    sqrt (b^2) = sqrt (576)

    b = 24
