<span><u><em>The correct answers are: </em></u>
B) have the same vertex
C) be congruent.

<u><em>Explanation</em></u><span><u><em>: </em></u>
Vertical angles are defined as opposite angles that <u>share only a vertex</u>. This definition is why B is true.
Since they are opposite angles, that means that the sides of one angle will be opposite the sides of the other; since this is true, the angles must be <u>congruent</u>.</span></span>

Answer: Vertical angles must have same vertex and be congruent.

Step-by-step explanation:

When two lines crosses each other , the opposite angles are known as vertically opposite angles or vertical angles where "vertical" refers to the vertex .

Also we know that Vertical angles theorem says that vertical angles are always congruent.

Therefore,  Vertical angles must have same vertex and be congruent.

Explain why 13233345364715 is a composite no.​
rodikova [14]

Answer:

A composite number has more than two factors.  In this case, the number 13233345364715 has more than two factors, so it is composite.  

Step-by-step explanation:

Numbers can be classified as prime or composite.  Prime numbers have only two factors, 1 and the number itself.  For example, 13 is a prime number because only 1 and 13 can be multiplied together to get 13.  However, a composite number has more than two factors.  In the case of the numer 13233345364715, I know that there are more than two factors because the number ends in 5, which means it has a factor of 5.  To confirm, divide 13233345364715/5 = 2646669072943. This large of a number may also have other factors, however, since you now know it has at least four factors, it is composite.

Input 
the value of the radius (\frac{d}{2}):
V=\frac{4}{3}\pi (2)^3

Solve using the Order of Operations:
V=\frac{4}{3}\pi (8)

V=\frac{4}{3}\pi \frac{8}{1}

V=\frac{32}{3}\pi

The Answer Is:
\boxed{V=33.510322}

I hope this helped!
