One angle of a parallelogram is eight times the measure of the exterior angle adjacent to it. Find the measure of all 4 interior angles b) Draw a diagram and label all vertices

Question

no rounding please give exact answer

Answer 1

The interior and exterior angles are supplementary, they add up to 180 degrees.

So we divide 180 by 8+1 to give us 20 degrees. One angle is 160° And the other is 20°. These are the angles of the parallelogram because of the intrinsic geometry of the figures.
