Answer:
100 : 40: 60: 160
Explanation:
The angles of a quadrilateral add up to 360
If the ratio of angles are 5:2:3:8, multiply each by x
5x : 2x: 3x: 8x These are the angles in the quadrilateral
5x+2x+3x+8x = 360
Combine like terms
18x =360
Divide by 18
18x/18 = 360/18
x =20
To find the angles of the quadrilateral, we can substitute for x
5x : 2x: 3x: 8x
5*20: 2*20: 3*20: 8:20
100 : 40: 60: 160
