What you have here is a situation with two similar triangles. The triangle in the lower left is similar to the triangle in the upper right - I've included an image with "cutouts" of those triangles so you can see the similarities. Similar triangles have a very important property: the ratios of their corresponding sides are equivalent. Here, we can set up a ratio between the sides of length 64 and x on the larger triangle, and the corresponding sides of length x and 36 on the smaller triangle. Setting the two equal to each other, we have

$\frac{64}{x}= \frac{x}{36}$

Multiplying both sides of the equation by 36 and x, we get

$64\cdot36=x^2$

finally, we take the square root of both sides of the equation to find x:

$\sqrt{64\cdot36}=x\\
\sqrt{64}\sqrt{36}=x\\
8\cdot6=x\\
48=x$

Four points are always coplanar if they: Check all that apply. A. lie on the same line. B. lie on different planes. C. lie on di

kotykmax [81]

D. lie in the same plane.

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.

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.

Finally, the correct answers are A. and D.
