Mathematics

$sec\ x = \frac{25}{24}$

Step-by-step explanation:

Given

$sin\ x = -\frac{7}{25}$

$cot\ x = -\frac{24}{7}$

Required

Determine sec x

Sec x is calculated as:

$sec\ x = \frac{1}{cos\ x}$

Multiply by sin x/sin x

$sec\ x = \frac{1}{cos\ x} * \frac{sin\ x}{sin\ x}$

$sec\ x = \frac{1}{sin\ x} * \frac{sin\ x}{cos\ x}$

$sec\ x = \frac{1}{sin\ x} * \tan\ x$

$tan\ x = \frac{1}{cot\ x}$

$sec\ x = \frac{1}{sin\ x} * \frac{1}{cot\ x}$

The equation becomes:

$sec\ x = \frac{1}{-7/25} * \frac{1}{-24/7}$

$sec\ x = \frac{-25}{7} * \frac{-7}{24}$

$sec\ x = \frac{25}{24}$
