evaluate cos(162°). Round to 2 decimal places.
My answer:-0.95
Correct, DR !!!!
162° lies in the second quad.....it should take on a negative value for the cosine....
[ Note.....Math Guy.....you were in radian mode, rather than degree mode.......a common mistake !!! ]
I get that the cosine of 162 is 0.20 but geometry is not my area of expertise.
