Which trigonimetric function would you use to solve the problem?
If T = 55° and RT = 5, find RS.
a. tan or cot
c. cos or sec
b. sin or csc
d. sin or cos

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.

not sure but it may be b, as i said i'm not sure.
