6.0/sin M = 10.0/sin 72
6.0/sin M = 10.0/sin 72,
Sin(72)=0.9510565
6.0/sin M = 10.0/0.9510565
6.0/sin(M)=10.514622 cross multiply
6.0=10.514622 x sin(M) divide both sides by 10.514622.
Sin(M)=0.5706339
M=~34.79 degrees.
\(\frac{6}{sin M}= \frac{10}{sin72}\)
\(M=asin[6(\frac{sin72}{10})]\)
which is about 34.79 degrees
