Use the diagram to complete the statement. Given JKL, sin (38) equals-

(Diagram is a right triangle. Angle K is 52 degrees and angle L is 38)

cos (38)

cos (52)

tan (38)

tan (52)

Cos (52). Sine and Cosine are cofunctions so to convert from one to the other you subtract the value from 90 to get the other function. 90-38 = 52. you can check this by putting both into a calculator. (in degree mode on calculator)

sin (38) = 0.61566 ...

cos (52) = 0.61566 ...
