The sum of the two angles, which are obtained when two lines intersect, is equal to 50 °. Find these angles.

Two intersecting straight lines form vertical and adjacent corners.

Adjacent angles add up to 180 degrees.

Therefore, the sought angles are not adjacent, hence they are vertical.

The vertical angles are equal to each other.

This means that each of them is equal to 50º / 2 = 25º.
