The measure of an angle of a parallelogram is 12 degrees less than 3 times the measure of an adjacent angle. find the measure of all the interior angels of the parallelogram.

• geometry -

so let one angle be x

solve for x

x + 3x-12 = 180

So now you have a pair of adjacent angles, take it from there.

• geometry -

x=48
