Which pair of functions are inverses of each other? O A. f(x) = – 2 and g(x) = 272
O B. f(x) = x + 6 and g(x) = 5x – 6
c. f(x) = and g(x) = 6 x3
O D. f(x) = 7x – 2 and g(x) = 2+2
6

About 3.06

Step-by-step explanation:

  We can use trigonometry functions to solve for AC. Let the ?, representing AC, be "x" in our mathematical work.

  Since we have the hypotenuse and x is adjacent to the angle given, I am going to use cosine.

      cos(θ) =

      cos(40) =

      0.766 ≈

      3.06 ≈ x

      x ≈ 3.06
