Question

the four angles of the quadrilateral are in the ratio 3 ratio 4 ratio 5 ratio 7 ratio find the largest angle​

Answer 1

Answer:

the largest angle is 140

Answer 2

Step-by-step explanation:

Let angles of a quadrilateral be 3x,4x,5x and 7x

Now ,

3x+4x+5x+7x=360. ( sum of angles of quad.)

19x=360

x=360/19

largest angle= 7x

=7 X (360/19)

=132.63
