Answer 1

Question :

which of the following can be angles of a quadrilateral 72° , 69°,105°, 109° find the solution

Given :

72° , 69°,105°, 109°

To find :

solution

Solution :

sum of all angles of quadrilateral is 360°

= 72° + 69° + 105° + 109

= 355°

= 355 ≠ 360

=> it is not a quadrilateral
