Answer 1

One thing for sure. The reciprocal trig function chart is needed to keep track on this.

Answer 2

Approach the problems like this, keeping the reciprocal relationships in mind.

Look at option D and test it.

The option is sec B = 6/5.

To test that, find cos B. Cosine is the reciprocal of the secant.

cos B = 4/6 = 2/3. The reciprocal of 2/3 is 3/2 which would be the value of sec B.
In the options, sec B is given as 6/5 so option D is WRONG.

Answer 3

Look at the other options following the format above.
