Use trigonometric expressions to build an equivalent trigonometric identity with the given expression: (1-cos^2(x))(1+cos^2(x))/cos^2(x) = ?
a. sec^2(x) + cos^2(x)
b. cos^2(x)
c. tan^2(x)
d. sin^2(x) + sec^2(x) -1

answer:   x*94 +688*6   = 267*100

94x+4128=26700    

94x=22572     /94

x=240.128

step-by-step explanation: mark as brainlest reallly need it thx

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
