There are two -main- approaches to answer this problem. By using the sine identity, or applying law of sines.
We'll do the sine trig. identity, as it is the most effective.
Given an angle '
' in a right triangle, '
' is defined as the opposite side of the triangle to the given angle, over the triangle's hypotenuse.
So, for this setup:
Now, we solve for x:
So, answer is 3.4

Answer:
D
Step-by-step explanation:
The arcsine () function of x is defined as the inverse sine function of x when -1≤x≤1.
So, when
we have that
This gives us the domain of the function
The range of the function is
so the range of the function
is the same (options A and C are false).
When x=-4,
So, option B is false and option D is true.
