Answer:
Meter
Step-by-step explanation:
kilometers are just too big to measure a chair, millimeters are to small to measure a chair, and centigrams measure mass. So meters would make the most sense.
x would be 54 degrees
Since x lies on a straight line, and it gives you the other angle (126) just subtract 180 and 126.
180 - 126 = 54
