Question

The supplement is 103° because
180° - 77° = 103°
The supplement of the angle is
• -103° because
77°- 180°= -103°
The supplement of the angle is 77°
• because supplementary angles are
congruent.
• The supplement of the angle is 13°
because 90° - 77° = 13°

Answer 1

The correct statement is:

The supplement is 103° because 180° - 77° = 103°.

Supplementary angles add up to 180°, so the supplement of an angle that measures 77° is 103°.
