Answer:
Line CD
Step-by-step explanation:
% is used in a lot of programming languages as the modulo operator.
![a\%b=c\iff a\equiv c\mod b](https://tex.z-dn.net/?f=a%5C%25b%3Dc%5Ciff%20a%5Cequiv%20c%5Cmod%20b)
which is to say, the remainder upon dividing
![a](https://tex.z-dn.net/?f=a)
by
![b](https://tex.z-dn.net/?f=b)
is
![c](https://tex.z-dn.net/?f=c)
.
When you divide any integer by 2, you can get either a remainder of 0 or 1. So in your example,
![x\%2\neq0](https://tex.z-dn.net/?f=x%5C%252%5Cneq0)
refers to all numbers
![x](https://tex.z-dn.net/?f=x)
between 1 and 9 that are not perfectly divisible by 2. In other words,
![x\%2\neq0](https://tex.z-dn.net/?f=x%5C%252%5Cneq0)
refers to those
![x](https://tex.z-dn.net/?f=x)
that are odd. (This assumes
![B](https://tex.z-dn.net/?f=B)
is a subset of the integers.)
Answer:
The other angle's measure is 2/3 (54) = 108/3 = 36 degrees.
Answer:
(C) 2√15
Step-by-step explanation:
Recognize that all the triangles are right triangles, so are similar to each other. In these similar triangles, the ratio of the short side to the long side is the same for all.
... CB/CA = CT/CB
... CB² = CA·CT = 10·6 = 60 . . . . . . . . . . multiply by CA·CB; substitute values
... CB = √60 = 2√15 . . . . . . . take the square root; simplify

<em>Comment on this solution</em>
The altitude to the hypotenuse of a right triangle (CB in this case) divides the hypotenuse into lengths such that the altitude is their geometric mean. That is ...
... CB = √(AC·CT) . . . . as above
This is true for any right triangle — another fact of geometry to put in your list of geometry facts.
