Answer 2

Given : PQRS is a quadrilateral with Q = 65° and S = 105°

∠P and ∠R  are in ratio  3 : 7

To Find : ∠P and ∠R

Solution:

∠P and ∠R  are in ratio  3 : 7

∠P = 3A

∠R = 7A

∠P + ∠Q + ∠R + ∠S = 360°  ( sum of angles of a Quadrilateral )

=> 3A + 65° + 7A + 105° = 360°

=> 10A  = 190°

=> A = 19

∠P = 3A = 3 x 19 = 57°

∠R = 7A = 7 x 19 = 133°
