whats the answer

Answer 2

your calculator probably doesn't do "secant". But sec is 1/cos
so do cos(85) (in degree mode, not radian mode)
then "invert it": 1 / ANS or x^-1 if you have that key

or type
1/cos(85 degrees)=
in the google search window

Answer 3

You should know it is not the answer, it is how you get it that counts.
