Pwease Help :,(

Hello Asinus, Thank you very much for the answer. I got the same answer as well, but I am not exactly sure how to convert it to radians...

Do you know any I can do that?

Hey Guest! The formula used for the Radian Conversion is -> Radians = (Degrees × π)/180°. 

The result is given in radians.

Set the 2.0 calculator to rad. Then give arccos.
