Express as functions of positive acute angles:

1. Sin 240 degree

2. Tan 130 degree

3. sec 305 degree

4. cos 95 degree

5. csc 185 degree

1. Sin 240 degree = - sin (240 - 180 degree) = - sin (60 degree)

2. Tan 130 degree = - tan (180 - 130 degree) = - tan 50 degree

3. sec 305 degree = sec (360 - 305 degree) = sec (55 degree)

4. cos 95 degree = - cos (180 - 95 degree) = - cos 85 degree

5. csc 185 degree = - sin 5 degree
