    Well, the sum of all the angles in a quadrilateral will always be 360 degrees. For example, on the first one, 100+87+106+x = 360, so x = 67 degrees. Can you do the rest by yourself now knowing that? I don't want to take away all of the practice you'd get from these.

    The sum of the angles of triangles add up to 180, but all quadrilateral's angles add up to 360. And with #42 and #46, when it has the little red square in the corner, that means it's a right angle and so is equal to 90 degrees. Can you work them from there? (:
