Answer:

Step-by-step explanation:
We are given the equation:

First, we can divide everything by 2:

Notice that we have an equation in quadratic form. Namely, if we make a substitution where u = sin(x), we acquire:

Solve for u. Factor:

Zero Product Property:

Solving for both cases:

And by substitution:

For the first case, recall that sin(x) is -1/2 for every 7π/6 and every 11π/6. Hence, for the first case, our solutions are:

Where n is an integer.
For the second case, sin(x) is -1 for every 3π/2. Thus:

All together, our solutions are:

Answer:
The correct answer would be D I believe.

Answer:
x = 9.6
Step-by-step explanation:
Before we can figure out what x is, we need to figure out what the unlabeled side is. To figure that out, multiply the hypotenuse (12) by the sine of the angle labeled (34)
12 * sin(34)
<em>sin(34) equals 0.559192903470747; I'll round it to 0.6 for convenience.</em>
12 * 0.6
<em>Now simply multiply 12 by 0.6 to get 7.2.</em>
The unlabeled side is approx. 7.2 units long.
Now we know what the unlabeled side is. Now, to find x, find the square root of 12 squared minus 7.2 squared.
x = √12² - 7.2²
<em>12 squared is 144; 7.2 squared is 51.84.</em>
x = √144 - 51.84
<em>Subtract 51.84 from 144 to get 92.16.</em>
x = √92.16
<em>The square root of 92.16 is 9.6 (on the spot!).</em>
x equals 9.6.
