I have several otehr along the same lines an just wanna make sure im not doing them incorrectly.
Thanks, -Nick.
Answer by RAY100(1637) (Show Source): You can put this solution on YOUR website!
sin theta = .500
.
arc sin theta = 30 degrees
.
check sin 30 = .500,,,,,,ok
.
Now there is another answer,,,,,,working off the ref line at 180 deg
.
180-30 =150 deg
.
check sin 150 = .500,,,,,ok
