6*3 =18 so the height of the parralelogram is 3 . Side is 6. Cathet against angle of 30 degrees is half the hypothenuse. SO A)

area = 6 * h
18 = 6 * h
h = 3

6^2 = 3^2 + x^2
x = 3√3

ratio of sides = 3 : 3√3 : 6 THIS IS 30 : 60 : 90 triangle
So answer should be 30. A.

A of parallelogram = h*b
h*b=18
h= 18/6 = 3

sin x = 3/6 = 1/2
x=30
