Answer:

x = 21° or 339°

Step-by-step explanation:

We are given that cos x = 0.9341.

So, cosine of x is positive and then x can be in first quadrant or fourth quadrant.

Now, [tex]x = cos^{- 1}(0.9341) = 20.91^{\circ}[/tex] ≈ 21° (to the nearest degree)

So, x = 21° or (360 - 21)° = 339° (Answer)
