In a parallelogram, the sum of two angles is 86 degrees. Find the angles of the parallelogram.

Let us determine what each of the two acute angles of the indicated parallelogram will equal, when from the condition of the task we know that in total they amount to 86 °:

86: 2 = 43.

From the current school curriculum in geometry, we know that the sum of the angles that belong to one side of the parallelogram will equal 180 °. Then we determine what each of the obtuse corners of our geometric figure will equal:

180 – 43 = 137.

Answer: Two angles of the parallelogram will be 43 ° each, two more will be 137 °.
