well, the points give you the opposite side, and the adjacent side. The hypotenuse must then be sqrt (25+16). So now one knows all three sides.
Use the formulas for sine, cosine, and tangent, then invert them for the other three.

so R would be sqrt41 and then sin=4/sqrt41 cos=5/sqrt41 and so on and so forth right?

The values of the six trig. functions should be:
sin(theta) = 4

sqrt(41)
cos(theta) = 5

sqrt(41)
tang(theta) = 4/5
csc(theta = sqrt(41)

4
sec(theta) = sqrt(41)

5
cot(theta)= 5/4
