Find the missing value to the nearest whole number.

cos xº = 0.39

67°

Step-by-step explanation:

Apply the inverse cosine function to both sides, obtaining:

x = arccos 0.39

Using a calculator, obtain the value of x:

x = 1.17 (radians)

or

       1.17         180°

x = ·  =  67 degrees (to the nearest whole degree)
