Question

In a 3-4-5 right triangle which expression would provide the measure of the smallest acute angle

Answer 1

The possible expressions for the measure of the smallest acute angle

     $sin\:\theta =\frac{3}{5}\:or\:\theta =sin^{-1}\left(\frac{3}{5}\right)$

     $cos\:\theta =\frac{4}{5}\:or\:\theta =cos^{-1}\left(\frac{4}{5}\right)$

     $tan\:\theta =\frac{3}{4}\:or\:\theta =tan^{-1}\left(\frac{3}{4}\right)$

These three expressions are the possible measure of the smallest acute angle.
