The formula to calculate the secant of an angle is:
\[ \sec X = \frac{H}{A} \]
Where:
The secant can also be calculated using the inverse of the cosine:
\[ \sec X = \frac{1}{\cos X} \]
The secant is defined as the inverse of the cosine of a value. It is the ratio of the length of the hypotenuse to the length of the adjacent side in a right-angled triangle.
Let's assume the following values:
Step 1: Calculate the Secant (sec X):
\[ \sec X = \frac{10}{8} = 1.25 \]
The secant of the angle is 1.25.
