Question

Q.5 Angles of a quadrilateral are in the ratio 3:4:4:7. Find all the four angles of the quadrilateral .

guys help!!!!!​

Answer 1

let the angles of the quadrilateral = 3x, 4x, 4x, 7x

sum of angles of a quadrilateral = 360⁰

3x + 4x + 4x + 7x = 360⁰

18x = 360⁰

x = 360/18

x= 20⁰

3x = 3 × 20 = 60⁰

4x = 4 × 20 = 80⁰

7x = 7 × 20 = 140⁰

Therfore, the four angles of the quadrilateral are 60⁰, 80⁰, 80⁰ and 140⁰

Answer 2

Step-by-step explanation:

total angel of quadrilateral are 360

so

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

18x=360x

=20

so angels are

3*20=60

4*20=80

4*20=80

7*20=140
