Question

the 4 angle of the quardilateral are in the ratio 3: 4: 5: 6 . find the angle.

Answer 1

sum of all angles of quadrilateral=360*
sum of ratio=3+4+5+6=18
360/18=20*
therefore the angles are 60*,80*,100*,120*

Answer 2

$3x+4x+5x+6x=360$ (angle sum property of a quadrilateral)
⇒$18x=360$
⇒$x = \frac{360}{18} =20$
⇒The angles are :
3*20=60
4*20=80
5*20=100
6*20=120
(All measurements are in degrees).
