Given, sec theta = 3x.

tan theta = 3/x.

Now, As we know that,,

sec^2theta - tan^2theta = 1.

; (3x)^2 - (3/x)^2 = 1.

; 9x^2 - 9/x^2 = 1.

; 9(x^2 - 1/x^2) = 1.

Answer 2

Step-by-step explanation:

the explanation of the answer is given above !! sry bro or sis make it as

sec²∅ + tan²∅ = 1 ( as we know )
