Answer 2

In a parallelogram opposite angles are equal

And consecutive angles are supplementary

So,

sum of the smallest angle and greatest angle = 180

greatest angle of a parallelogram is 30° more than twice the smallest angle

Let the smallest angle = x

Then greatest angle = 2x +30

x +2x+30 = 180

x + 2x = 180 - 30

3x = 150

x = 150/3

x = 50

Smallest angle = 50

Greatest angle = 2x +30 = 130
