so you know law of sines
does this make sense?
\(\large\frac{\sin(87)}{x}=\frac{3}{.75}\)
OpenStudy (anonymous):
write it clearly
OpenStudy (anonymous):
oh ok
OpenStudy (anonymous):
how is it 87
OpenStudy (zzr0ck3r):
we know one angle is 90, we know another is 3, they must all add to 180, so that leaves one option for the third angle
