A parallelogram has one angle that measures 50°. What are the measures of the other three angles in the parallelogram?

130°, 50°, 130°

Step-by-step explanation:

Two opposite angles of parallelogram are always congruent, so the measure of angle opposite to the angle 50° is 50° too.

Two consecutive angles of parallelogram always are supplementary (add up to 180°), so the angle consecutive to the angle 50° has the measure of

180° - 50° = 130°

Angle opposit to 130° angle has the measure of 130° too.
