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

Sum of the angles = 360 o

 

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

 

solve fo x  = 30            now YOU can figure which angle is the largest.....cheeky
