Given `tanA=4/3`, find the other trigonometric ratios of the angle A.

Explanation

To find the other trigonometric ratios of angle A given that \( \tan A = \frac{4}{3} \), we can follow these steps:

### Step 1: Understand the relationship of tangent
The tangent of an angle in a right triangle is defined as the ratio of the opposite side (perpendicular) to the adjacent side (base). Therefore, we can represent this as:
\[ \tan A = \frac{\text{Opposite}}{\text{Adjacent}} = \frac{4}{3} \]
This means we can take the opposite side (perpendicular) as \( 4k \) and the adjacent side (base) as \( 3k \), where \( k \) is a positive constant.
