Question

the angle of aquadrilateral are in the ratio 3:5:7:9. Find the measureof each of these angle.​

Answer 1

Answer:

let the measure of each angle be 3x,5x,7x and 9x.

24x=360°(ASP OF QUADRILATERAL)

x=360/24

×=15

3x=45°

5x=75°

7x=105°

9x =135°

the measure of each angles of the quadrilateral are 45 ,75,105 & 135 degree each.

pls mark as brainliest.

Answer 2

let x be angle to quadrilateral

the angles are 3x, 5x,7x,9x

$3x + 5x + 7x + 9x = 360 \\ 24x = 360 \\ x = 15$

the angles is 3x ( 45°)

the angles is 5x is (75°)

the angles is 7x is (105°)

the angles is 9x is (135°)
