12. (8 points) Find sin (a) and cos (A), tan () and cot (f), and sec (a) and csc (B).

sin alpha=opposite/hypotenuse= 1/(sqrt(1+9))=1/sqrt10

cos beta=adjacent/hypotenuse=1/sqrt10

tan alpha=opposite/adjacent=1/3

cot beta=adjacent/htpotenuse=1/3

sec alpha=hypotenuse/adjacent=sqrt(10)/3

csc beta=hypotenuse/opposite=sqrt10
