Answer:
c = √(42² +35² -2·42·35·cos(120°))
Step-by-step explanation:
The third side can be found using the Law of Cosines. It will tell you ...
c² = a² +b² -2ab·cos(C)
where C is the angle opposite the third side (c). For the given side lengths, then the third side can be found from ...
c = √(42² +35² -2·42·35·cos(120°))

<em>Additional comment</em>
You have not provided answer choices to this "which ..." problem. So the above equation may be different from any on your list. We expect your answer choices may leave the equation in the form <em>c² = ...</em>.
Firstly, solve 38C15.
Then solve 42C12.
Compare your answers.
The goal here is to see if 38C15 = 42C12.
Here is the formula:
nCr = n!/(r!(n - r)!
Go for it.
Answer:
No it is not proportional
Step-by-step explanation:
You cant multiply each of the inputs by a constant number to get the output.
There is only 2 of them that you can, but the other 2 no. And you want he whole table so you need all of the inputs not just some. So no, its not proportional.
Hope this helped!
Answer:
32
