 Given \: in \: Quadrilateral \: PQRS ,\\\angle P = 5x , \: \angle Q = 3x , \: \angle R = 4x ,\\and \: \angle R = 4x

 \underline {\blue { By \: Angle \:Sum \: Property : }}

 \pink { Sum \:of \: 4 \:angles \: in \: Quadrilateral }

\pink {are \: supplementary }

 \implies \angle P + \angle Q + \angle R + \angle S = 360\degree

 \implies 5x + 3x + 4x + 6x = 360\degree

\implies 18x = 360\degree

 \implies x = \frac{360}{18}

 \implies x = 20

/* Putting x = 20 */

 \angle P = 5x = 5\times 20 = 100\degree

 \angle Q = 3x = 3\times 20 = 60\degree

 \angle R = 4x = 4\times 20 = 80\degree

 \angle S = 6x = 6\times 20 = 120\degree

 Greatest \: angle \: of \: Quadrilateral \:PQRS \\ is \: \angle S

Therefore.,

 \red {Greatest \: angle \: of  \:PQRS}\green { = \angle S }
