Answer:
A) -0.18 rad
Step-by-step explanation:
arcsin(x) = a means that sin(a) = x
For example
arcsin(1) = pi/2.
It means that pi/2 is the value for which the sin is equals to 1.
arcsin(-0.18)
This is the value of x for which sin(x) = -0.18. This happens for x = -0.18 rad.
So the correct answer is:
A) -0.18 rad
