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**
