The sin ratio is the side opposite the reference angle over the hypotenuse.  If Z is our reference angle, then the side opposite it has a length of 32.  The hypotenuse has a length of 40.  Therefore, the sin of Z = 32/40.  We will reduce that to sin Z = 4/5.  First choice above.

Use the point (-6,-8) to give the six trigonometric functions
vfiekz [6]
You can't exactly get the trigonometric functions using a point unless it's a vector,

so tanx = -8/-6 = 4/3 and from it we can get the other functions

sinx = -4/5
cosx = -3/5
secx = -5/3
cscx = -5/4
cotx = 3/4
