A quadrilateral has angles of q, 5q + 15 , 3q - 55, and 4q - 20. Find the largest angle of the quadrilateral, in degrees
The number of degrees in the interior angles of a quadrilateral is 360o.
Solve this equation for q: (q) + (5q + 15) + (3q - 55) + (4q - 20) = 360
and, using that value for q, find:
5q + 15 =
3q - 55 =
4q - 20 =
