n = 5 + 5/2
n = 5 + 2.5
n = 7.5
-----------
check
7.5 - 5/2 = 5
7.5 - 2.5 = 5
5 = 5
the answer is good

Answer:
mZ is 72°
Step-by-step explanation:
The three points form a right triangle with a 90° angle at Y. Since a triangle has 180°, first subtract 180-90=90°. Next, subtract 90-18=72 because mX=18°. Therefore, mZ is 72°.
