If `sin theta = 5/7` what is `cos theta` and `tan theta`?

Explanation

To solve the problem where \( \sin \theta = \frac{5}{7} \), we need to find \( \cos \theta \) and \( \tan \theta \).

### Step 1: Understand the relationship of sine in a right triangle
Given \( \sin \theta = \frac{\text{perpendicular}}{\text{hypotenuse}} \), we can represent this in a right triangle where:
- The perpendicular side (opposite to angle \( \theta \)) is \( 5 \).
- The hypotenuse is \( 7 \).

### Step 2: Use the Pythagorean theorem to find the base
