please help i'll give medal!!!!Angle MNO is formed by segments MN and NO on the coordinate grid below: Angle MNO is rotated 180 degrees counterclockwise about the origin to form angle M′N′O′. Which statement shows the measure of angle M′N′O′?a. m∠M′N′O′ = 90 degreesb. m∠M′N′O′ = 180 degreesc. m∠M′N′O′ = 2 × m∠MNOd. m∠M′N′O′ = m∠MNO
