The angles of a quadrilateral are x, 5x + 15 degrees, 3x - 25 degrees, and 4x - 20 degrees. Find the measure of the largest angle of the quadrilateral.

Thanks!

The sum of all interior angles of any quadrilateral = 360 degrees

x + [5x +15] + [3x - 25] + [4x - 20] = 360

13x = 360 - 15 + 25 + 20

13x = 390

x = 30 - degrees.

5*30 + 15 = 165 - degrees - the largest angle.
