a. solve the equation for theta, assume all angles acute:

1. csc(20degrees)= sec(theta + 10degrees)

2. cos (3theta) = sin (40degrees - theta)

b. find the value of the angle:

1. sin B = 0.2840

2. cot A = 3.5261

3. sec A = 3.046

These questions use trigonometric identities that are listed here:
