Question

In quadrilateral PQRS if angle P=60and q:R:s=2:3:7 then find the measure of s​

Answer 1

let the angle q, R, s = 2x ,3x, 7x respectively

using angel sum property

<p +<q + <R + <s = 360°

60° + 2x +3x +7x = 360°

12x = 360° - 60°

12x = 300°

x = 300°/12

x = 25°

hence

<s = 7x = 7*25

<s = 175°
