Question

Angle MN'O is formed by segments MN and NO on the coordinate grid: A coordinate plane is shown. Angle MN'O has vertices at negative 4 comma 4 and negative 2 comma 2 and negative 4 comma 1 and measures 71.57 degrees. Angle MN'O 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 degrees
B. m∠M’N’O’ = 180 degrees
C.m∠M’N’O’ = 2 × m∠MN'O
D. m∠M’N’O’ = m∠MN'O

Answer 1

B

im pretty sure

best of luck hope i help chu ^-^

Answer 2

Hello,

B. m∠M’N’O’ = 180 degrees seems like this should be the answer.

Hope this helps
