dont u just rearrange for sin(x)
then do arcsin of that
u get the principal value
do 180 - that
for the 2nd value
and you know what the angles are so u can work out inside brackets
i did this
0.636 comes from sin^-1(0.594)
oh yeh in radians
yh
oh wait
u got -60 smth
- 365
u get like 300 smth
thats one of the answers
u cant force it positive
,w arcsin[(14-11.7)/3.87]
