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

 

Thank you!

The angles of a quadrilateral add up to 360 degrees.  If you add up the angles, and solve the equation, you get q = 25.  Therefore, the largest angle is 5q + 15 = 140 degrees.
