For the angle M, the perpendicular side is NO = 5 and hypotenuse side is MO = 11.
Determine the measure of angle M.
[tex]\begin{gathered} \sin M=\frac{NO}{MO} \\ \angle M=\sin ^{-1}(\frac{5}{11}) \\ \angle M=\sin ^{-1}(0.4545) \\ =27.035 \\ \approx27 \end{gathered}[/tex]
So expression for angle M is,
[tex]\angle M=\sin ^{-1}(\frac{5}{11})[/tex]
The measure of angle M is 27 degree.
