Question

the angles of a quadrilateral are in a ratio of 3:4:5:6 then find the largest angle​

Answer 1

Answer:

Let the angles of a quadrilateral are 3x, 4x, 5x, 6x.

then, 3x+4x+5x+6x =360°

18x =360°

x= 360°/18

x=20°

the largest angle of a quadrilateral are

20×6 120°

Answer 2

Answer:

the angle of the sum = 180

3x + 4x + 5x + 6x = 180

18x = 180

X = 180/ 18

X = 10
