Question

PQRS in a quadrilateral with angle Q= 65° and angle S=105°. If angle P and angle R are the ratio 3:7, find angle P and angle Reply​

Answer 1

Answer:

let angle p = 3x

angle r=7x

therefore sum of angles of quadrilateral is 360

65+105+7x+3x=360

170+10x=360

10x=360-170

x=190/10

x=19

therefore angle p= 3× 19= 57

angle q=7×19= 153
