Answer :
The angle whose sin is 0.78 is either 51.26 degrees or 128.74 degrees.
(rounded)
There's no simple way to calculate this. You just have to look it up in a book
or punch it into your calculator.
sin (x)=0.78
x=[tex]sin^{-1} (0.78)[/tex]
x= 51.26° or 180°- 51.26°= 128.74°
x=[tex]sin^{-1} (0.78)[/tex]
x= 51.26° or 180°- 51.26°= 128.74°
