Question

For a standard-position angle determined by the point (x,y), what are the values of the trigbonometric functions?
For the point (16,12) find sin(theta) and cos(theta)

Answer 1

first you need to find the value of c in the diagram below

Answer 2

once you have the value of c, you can find sin(theta) and cos(theta)

Answer 3

i got sin 12/20 and cos 16/20

Answer 4

12/20 reduces to 3/5
16/20 reduces to 4/5

Answer 5

OKay thanks :)

Answer 6

yw

Answer 7

quick question
if thats your triangle what would you use to find x?
