?(1 point)
Responses
The supplement of the angle is −103°
because 77°−180°=−103°
.
The supplement of the angle is negative 103 degrees because 77 degrees minus 180 degrees equals negative 103 degrees .
The supplement of the angle is 13°
because 90°−77°=13°
.
The supplement of the angle is 13 degrees because 90 degrees minus 77 degrees equals 13 degrees .
The supplement is 103°
because 180°−77°=103°
.
The supplement is 103 degrees because 180 degrees minus 77 degrees equals 103 degrees .

1 answer
The correct response is:
The supplement is 103° because 180°−77°=103°.
Supplementary angles are two angles that add up to 180°. In this case, to find the supplement of an angle that measures 77°, you subtract 77° from 180°:
180° - 77° = 103°.
So, the supplement of a 77° angle is indeed 103°.
