Find x if cos (x) =.1412

0.99999696 is your answer I am pretty sure.

To find the value of an angle X, you need to divide both sides of the equation by cosine to isolate x. This would give you cos-1 (inverse cosine or secant) equals. 1412. Then you can use a calculator to evaluate, making sure that it is in degrees, not radians. The cos-1 (.1412) is approximately 81.88270898
