Find the exact real value of arcsinthe quantity negative one half.

210 or 330 degrees  for  angles between 0 and 360 degrees.

Step-by-step explanation:

Arcsin (1/2) =  30 degrees if the angle is in the first quadrant.

The sine is negative in the third and fourth quadrants so arcsin (-1/2)

= 210 or 330 degrees  for  angles between 0 and 360 degrees.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
