If N is in the interior of ZMPO, find mZNPO if mZMPN= 57° and mZMPO = 81º.
A. 24°
B. 43°
C. 91°
D 138°

A

Step-by-step explanation:

m∠MPN + m∠NPO = m∠MPO

m∠MPN is an acute angle. Because it's 57°, less than 90°

m∠AOC is 81° , so it's an acute angle, like m∠MPN

To find m∠NPO , just subtract m∠MPN from m∠MPO

81° = 57° + m∠NPO

m∠NPO = 81° - 57°

m∠NPO = 24°

Option A

So, m∠NPO is an acute angle. Because it's 24°, less than 90°

more about angles: Right angle = exactly 90° , Straight angle = exactly 180°, Full angle = exactly 360°
