Answer 4

I know the first step it to find the radius

Answer 5

how you think it ? first you need drawing this point in the coordinates plane and after drawing this angle

Answer 6

Never mind, I figured it out

Answer 7

can you post it here ?

Answer 8

Find the radius \[r=\sqrt{-3^2+1^2}\]

Answer 9

which equals approx 3.2

Answer 10

Then just solve for each one

Answer 11

sin=y/r cos=x/r and tan=y/x

Answer 12

are we done here?

Answer 13

yes i think you are right

Answer 14

ok thx

Answer 15
