Angle X measures 110 degrees. If angle X is rotated 60 degrees, what is the measure of angle X′? (4 points)
0 degree
60 degrees
110 degrees
170 degrees
0 degree
60 degrees
110 degrees
170 degrees
If angle X is rotated 60 degrees, the measure of angle X′ will be 110 degrees + 60 degrees = 170 degrees.
Therefore, the correct answer is 170 degrees.
Therefore, the correct answer is 170 degrees.
