Question 770233
find the exact value of the indicated trigonometric function of omega, if omega is an angle in standard position whose terminal side contains the given point. 
(12,16); find sin omega
***
You are working with a reference right triangle in quadrant I
hypotenuse=&#8730;(12^2+16^2)=&#8730;400=20
sin omega=16/20=4/5
cos omega=12/20=3/5
tan omega=sin/cos=4/3
