Answer:
1) yes and no you cant tell most the time but using common sense you can tell.
2)Yards, feet, inches, pounds, quarts, and miles are all part of the English system of measures. they are related because they all deal with unit of distance 
3), the distance of a road is how long the road is. In the metric system of measurement, the most common units of distance are millimeters, centimeters, meters, and kilometers. they are related because they also deal with distance in metrics.

Answer:
   12/13
Step-by-step explanation:
The length of the segment from the origin to the terminal point is ...
   r = √((-5)² +12²) = √169 = 13
The sine of the angle is the ratio of the y-coordinate to this distance
   sin(θ) = y/r = 12/13
_____
Additional comment
The other trig functions are ...
   cos(θ) = x/r = -5/13
   tan(θ) = y/x = -12/5
This is a 2nd-quadrant angle, where the sine is positive, but the cosine and tangent are negative.
