Question

a parallelogram has one angle that measures 40. what are the measures of the other three angles in the parallelogram?

Answer 1

A parallelogram will always add up to 180 degrees. So if one side is 40 degrees, all you have to do is subtract 180 degrees from 40 degrees and divide by 3 and there you go!!

Answer 2

Since one side is 40°, you subtract that from 180.

180° - 40°= 140°.

So therefore your missing side lengths are 140, 40, and 140.

hopefully this helps
