Question

Find x if cos(x)=.1412

Answer 1

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

Answer 2

0.99999696 is your answer I am pretty sure.
