The ratio between the angles of a quadrilateral is 3 : 4 : 6 : 7. Half the second largest angle of the quadrilateral is equal to the smaller angle of a parallelogram. What is the value of adjacent angle of the parallelogram?
A$136^∘ $
B$126^∘$
C$94^∘$
D$96^∘$

Correct answer is: 126

Explanation:

3x+4x+6x+7x=360

=20x=360o

x=18o

Therefore, smaller angle of the parallelogram = 6x2

=3x=54

Therefore, Adjacent angle of parallelogram

=18054=126
