Question 943775
your angle is 26.56505118 degrees.


you get sin(y) = n / n*sqrt(5) which is equal to 1/sqrt(5)


you get cos(y) = 2n / n*sqrt(5) which is equal to 2/sqrt(5)


you get tan(y) = n / 2n = 1/2


use your calculator to get arcsin and arccos and arctan and they all point to 26.56505118 degrees.
