In `DeltaABC` , `angleA` is right - angled . If AB= 1 cm , AC =3 cm and BC = `sqrt(10)` cm , then find the values of cos B and sin C.

Explanation

To solve the problem, we need to find the values of cos B and sin C in triangle ABC, where angle A is a right angle. We are given the lengths of the sides: AB = 1 cm, AC = 3 cm, and BC = √10 cm.

### Step-by-Step Solution:

1. **Identify the Triangle and Angles**:
- We have triangle ABC with angle A as the right angle.
- The sides are defined as follows:
- AB = 1 cm (opposite to angle C)
