Question

9. If the ratio of angles in a quadrilateral is 1-2-3:4 then largest angle is
(a) 369
(b) 1440
(c) 1080
(d) 720
​

Answer 1

Answer:

Option b . 144°

Step-by-step explanation:

Let angles of quad be 1x , 2x , 3x , 4x

now sum of interior angles of quad

1x + 2x + 3x + 4x = 360

10x = 360

x = 36

angles of quad = 36°

72°

108°

144°

Largest angle = 144°
