dw:1369794012893:dw here sec a=hyppoteneus/adjacent so hp=5 and adj=3 so opposite side =4 by pythagorus thm so sin a=opposite/hypp=4/5

you said sec A=5/3 so the sec=hyp/adj. the hyp=5 and the side adjacent to angle A would be adjacent. Through pythagorean theorem you can find the other value because it is a right triangle

The trick with pythagorean theorem is that the "c" is always the hypotenuse

Csc=Hyp/opp so the opposite side from angle C is =3 and the hypotenuse is =5. so csc C =5/3
