The
angles of quadrilateral are in the
ratio 3:4.5:6 The
hargest of
these
angles is.​

Answer 1

Step-by-step explanation:

Let X be the common multiple

Then,

3x + 5x + 9x + 13x = 360 (As sum of angles of a quadrilateral is 360°)

30x = 360

x = 12°

The angles are

3x = 3*12 = 36°

5x = 5*12 = 60°

13x = 13*12 = 156°

9x = 9*12 = 108°

Answer 2

Answer:

120 degrees

Step-by-step explanation:

let the angles be 3x , 4x , 5x , 6x

sum of all angles of a quadrilateral = 360 degrees

therefore,

3x + 4x + 5x + 6x = 360

⇒18x=360

⇒x=360/18

⇒x = 20

∴ largest angle = 6 x 20 = 120 degrees
