Relative to angle A, this is how the sides of a right triangle would be labeled. |
The secant of angle A equals the length of the hypotenuse divided by the length of the adjacent side.
We could write:
sec(A) = hyp / adj
So, for example, if the length of the hypotenuse was 10 and the length of the adjacent side was 8, then we would write:
sec(A) = 10 / 8
sec(A) = 1.2500
