    ok... so for the 1st question let x be the smallest angle then the other 3 angles are x + 10, x + 20 and x + 30 and knowing the angles in a quadrilateral add to 360 you have an equation x + x + 10 + x + 20 + x + 30 = 360 so 4x + 60 = 360 just solve for x.

    well the smallest angle is 75... so if each other angle inceases by 10 degrees, what are the other 3..?

    4x + 60 = 360 - 60 -60 4x = 300 /4 /4 x = ?

    It would be 75, 85, 95, and 105. Those numbers added up would be 360.
