    Answer:

    31.5 ft

    Step-by-step explanation:

    Use the Pythagorean Theorem

    a² + b² = c²

    Plug in the knowns

    a² + 23² = 39²

    Subtract 23² from both sides

    a² = 39² – 23²

    a² = 1521 – 529

    a² = 992

    Take the square root of both sides

    a = 31.496031496

    Rounded

    a = 31.5 ft
