1) Since the question is about solving the arcsine of the angle whose measure is 0.848. When we calculate the arcsine, we are figuring out the measure of the angle given the value of the sine of this very angle.
2) So let's do this:
[tex]\sin ^{-1}(0.848)\text{ =57.994}\cong58[/tex]
2) So the angle whose sine is 0.847 is the sine of (57.994º)
