If cos a = 3 over 11, then which of the following is correct? sec a = 11 over 3 csc a = 11 over 3 sec a = 3 over 11 csc a = 3 over 11

 The answer is (a) sec A = 11 over 3.

Step-by-step explanation: Given that Cosine of an angle 'A' is 3 over 11,

i.e.,

And we need to find which one of the given four options is correct.

We have the following relations between cosine, secant and cosecant of an angle from trigonometry.

Therefore,

and

Thus, the correct option is (a)  sec A = 11 over 3.
