Find the measure of the unknown angle.71°?82°130°30°

The problem seems to be asking for the measure of an unknown angle in a polygon. However, the information provided is not clear.

In a polygon, the sum of the interior angles can be found using the formula (n-2) * 180, where n is the number of sides.

If the polygon is a quadrilateral (4 sides), the sum of the interior angles is (4-2) * 180 = 360 degrees.

If the given angles are part of the same polygon, we can add them up and subtract from 360 to find the unknown angle.

71° + 82° + 130° + 30° = 313°

So, the unknown angle would be 360° - 313° = 47°

However, without more context or a diagram, it's hard to give a definitive answer.
