    First, let's find angle A.

    The angles of a triangle always add up to 180 degrees.

    A + B + C = 180

    A + 45 + 55 = 180

    A + 100 = 180

    A = 80 degrees

    The longest side is always opposite the largest angle.

    Since A is the largest angle, the longest side is BC.

    The next largest angle is C, and the next longest side is AB.

    And the smallest angle B gives us the shortest side AC.

    Therefore, your answer would be BC, AB, AC.
