D. lie in the same plane.</span><span>
The definition of capillarity is that points are considered as co-planar when these points are on the same plane, so it is obvious that the answer D is true because this statement is the definition of capillarity. This is shown in Figure 1.

A. lie on the same line.</span><span>
If four points lie on the same line then there will be a plane that contains this line, therefore the definition is fulfilled. This is shown in Figure 2.

Answer:
SinA = 40/50
Step-by-step explanation:
I think it's just asking if you understand the trig ratios. You aren't really solving for anything.
SinA is 40 over 50 because 40 is opposite of <A and 50 is the hypotenuse.
Then, use the trig ratios to figure out the other problems.
