Answer:
A=54,B=72,C=108,D=126
AB is parallel to DC
AB is parallel to DC
Step-by-step explanation:
Let the ratio be the common multiple of x
angles=3x,4x,6x,7x
3x+4x+6x+7x=360( angle sum property)
20x=360
x=18
3x=54
4x=72
6x=108
7x=126
A=54,B=72,C=108,D=126
AngleA+ angle D=180(interior angle)
54+126=180
Therefore AB is parallel to DC
Angle B+angle A =180(interior angles)
72+54=180
Not possible
Therefore BC is not parallel to AD
