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 =(3)/(5)\:or\:\theta =sin^(-1)\left((3)/(5)\right)`


`cos\:\theta =(4)/(5)\:or\:\theta =cos^(-1)\left((4)/(5)\right)`


`tan\:\theta =(3)/(4)\:or\:\theta =tan^(-1)\left((3)/(4)\right)`

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