Question

lf the angles of a quadrilateral are in the ratio 1:4:5:8. Find the angles.​

Answer 1

Step-by-step explanation:

Let the angles of the quadrilateral be x,4x,5x and 8x . The sum of all the angles of a quadrilateral is 360° . or 18x = 360°. 20° , 4×20°=80° , 5×20°=100° and 8×20°=160°.

Answer 2

Answer:

Angle sum property of quardilateral ;

1x + 4x + 5x + 8x = 360'

18x = 360

x = 360 / 18

x = 20

1x = 20'

4x = 80'

5x = 100'

8x = 160'
