    Usually, the person posing the question tries to show what work they have. It doesn't have to be the complete solution obviously, but what ideas do you have? Do you have any equations, or can you figure out any of the angles?

    Don't worry about solving it. Can you find ANY of the angles? Write them in terms of X and Y to start

    Can you at least find angle DHC? I can't believe you can't find any angles in terms of X and Y

    Y = 70
    X = 20
    :)

    Now, How can I get HAB ?
