What is the supplement of an angle that measures 77°? (1 point)
O The supplement of the angle is 77 deg because supplementary angles are congruent.
The supplement is 103° because 180 ^ prime prime -77^ prime prime =103^ prime prime
O The supplement of the angle is -103 because 77^ prime prime - 180 deg = - 103 deg
The supplement of the angle is 13" because 90 ^ * -77^ * =13^ *
Choose of those 4
The correct answer is:
The supplement of the angle is 103° because 180° - 77° = 103°.
To find the supplement of an angle, we need to subtract the angle measurement from 180 degrees.
So, to find the supplement of an angle that measures 77°, we subtract 77 from 180:
180° - 77° = 103°.
Therefore, the supplement of the angle that measures 77° is 103°.
