    Use the fact the triangles are congruent.

    means, the corresponding sides and angles in each will equal each other

    Congruent means you can find all 3 angle and all 3 side measurements in both triangles.

    the really long side with the other really long side equals to each other the shorter one with the other and the last one with the last one of the other

    same goes for the angles

    So x=109 y=48 and x=48? How do you know the triangles are congruent?

    x = 109?

    Because of the SSS rule.

    i meant z=109.. wait so x doesn't equal 48 then... how do I find x?

    recall that all internal angles SUM UP to 180

    You can also use the fact the angles in a a triangle add up to be 180 degrees.

    okay so z=109, x=33, and y=38?
