How do you evaluate sec 23 deg. 2'? Trigonometry Right Triangles Trigonometric Functions of Any Angle 1 Answer Nghi N. Nov 27, 2015 Evaluate #sec 23^@2#' Ans: 1.09 Explanation: Call #x = 23^@2' = 23.033# #sec x = 1/(cos x)# . Find cos x #cos x = cos (23.033) = 0.92# #sec x = 1/0.92 = 1.09# Answer link Related questions How do you find the trigonometric functions of any angle? What is the reference angle?
