Multiple Choice Find the measure of ∠s. Three angles are formed on a line by 2 rays with a shared endpoint. One of the angles is marked as a right angle. One of the angles is marked s. The third angle is marked as 27 degrees. (1 point) Responses 63° 63° 153° 153° 68° 68° 148°
The sum of the angles on a line is always 180 degrees. Since one angle is a right angle (90 degrees) and the third angle is 27 degrees, you can determine the measure of angle s by subtracting these two angles from 180:
180 - 90 - 27 = 63 degrees
Therefore, the measure of ∠s is 63°.
