Given:

One of the supplement angles is 130°.

Concept used:

For supplementary angle: The sum of two angles is 180°.

For complementary angle: The sum of two angles is 90°.

Calculation:

The supplement angle of 130° = 180° - 130° = 50°

The complement angle of 50° = 90° - 50° = 40°

∴ The complement angle of the supplement angle of 130° is 40°

Mistake PointsPlease note that first, we have to find the supplementary angle of 130° & after that, we will find the complementary angle of the resultant value.
