Question

if the angles of a quadlateral are in the ratio of 4:3:4:7,. find the largest angle of the quadlateral​

Answer 1

Answer:

Answer of first question

Let the angles of

quadrilateral be 4x,3x,4x,7x

Sum of all angles of quadrilateral=360degree

4x+3x+4x+7x=360degree

=>18x=360

=>x=20degree

Angles of quadrilateral

4x=4×20=80degree

3x=3×20=60degree

4x=4×20=80degree

7x=7×20=140degree

(80,60,80,140degree)

pls mark me an brainalist answer

largest angle=140degree(Ans).

Answer 2

=> Let the angles of the quadrilateral

=> 4x, 3x, 4x, 7x

=> 4x + 3x + 4x + 7x = 360 degree ( Sum of all angles of a quadrilateral is 360 degree )

=> 18x = 360

=> x = 360/18 = 20

1st angle = 4 × 20 = 80

2nd angle = 3 × 20 = 60

3rd angle = 4 × 20 = 80

4th angle = 7 × 20 = 140

=> The largest angle of the quadrilateral

=> 7x = 7 × 20 = 140 degree

I hope this will help you dear..
