    To find the length of the ladder, you need to do Pythagorean theorem.

    50^2 + 30^2 = x^2

    2500 + 900 = x^2

    x^2 = 3400

    x = square root of 3400

    58.31 OR 10 root34

    To find the angle:

    tan theta = opposite/adjacent

    50/30 = 5/3

    theta = tan inverse of 5/3

    = 59.04
