Answer:
Step-by-step explanation:
It’s c
You have to get rid of 1/2 by multiplying it by its recriprocal which is like this:
1) 1/2 x 2/1 which equals to zero and you do the same to the other side.
2) -12 x 2/1 = -24x then multiply-24x with 7 which equals -168.
16-x= -24x -168
3) subtract 16 to the other side and subtract 24x with x
23x= -184
4) divide by 23 to isolate x and you get -8
5) x=-8
Answer:
<em>Proof in the explanation</em>
Step-by-step explanation:
<u>Trigonometric Equalities</u>
Those are expressions involving trigonometric functions which must be proven, generally working on only one side of the equality
For this particular equality, we'll use the following equation

The equality we want to prove is
Let's set the following variables:

And modify the first variable:

Now with the second variable

Knowing that

We compute the other two trigonometric functions of X and Y



Computing

Then

Now we replace all in the first equality:



Thus, proven
