    Problem with an Obtuse Triangle

    For this problem I must find the variable x and Angle A
    This is all the information I was given, but I'm not sure what to do
    I've got as far as using the Law of Cosines (ie not that far!)

    The given in this problem implies a contradiction.
    Note that X+(4-X)=4 so 49-16=33.
    But h=\sqrt{33}>5 which impossible as the hypotenuse is 5.
    So review the question. It is faulty as given.

    I'm sorry you're right
    I was able to solve it once I understood the whole base was 4-x not just that piece

    I was able to get x = -1 and angle A is 101.5
    x is negative because it goes to the left of the coords into negatives

    The problem was badly written, it is solved now
    Thanks
