If `sec theta=25/7` then find the value of `tan theta`.

Explanation

To find the value of \( \tan \theta \) given that \( \sec \theta = \frac{25}{7} \), we can follow these steps:

### Step 1: Use the identity relating secant and tangent
We know from trigonometric identities that:
\[ \sec^2 \theta = 1 + \tan^2 \theta \]
This means we can express \( \tan^2 \theta \) in terms of \( \sec^2 \theta \):
