Answer:
Answer would be A) tan or cot.
Step-by-step explanation:
In order to use the COS & SIN function, you would need to have hypotenuse.
Secant, and Cosecant are inverse function of Sin, Cos.
Therefore, you would still need to know the length of hypotenuse in order to get the value of Sec and Csc.
Because the length of hypotenuse is missing, you would have to use
Tan & Cot.
Hope this helped, have a nice day.
