What is the value of arcsin (-1/2) in degrees?

arcsin (-1/2) = 330 °

Step-by-step explanation: Given arcsin (-1/2).

It's a negative value for arcsin.

So, we could go in 4th quadrant. Because in 4th quadrant sin has a negative value.

In general sin 30 degree = 1/2.

But it's a negative 1/2.

So, sin (-30°) = -1/2.

So, we could say arcsin (-1/2)= -30°.

But if you want answer as a positive value. So, we could find reference angle of -30°, that would be 360+(-30) = 360 -30 = 330°
