    Answer:

    The width of the TV screen is 56 inches.

    Step-by-step explanation:

    We can find the width of the TV screen by using Pitagoras:  

    D^{2} = H^{2} + W^{2}

    Where:

    D: is the diagonal = 65 in

    H: is the height = 33 in

    W: is the width =?

    Then, the width is:

    W = \sqrt{D^{2} - H^{2}} = \sqrt{(65 in)^{2} - (33 in)^{2}} = 56 in

    Therefore, the width of the TV screen is 56 inches.

    I hope it helps you!
