In ` P Q R` , right-angled at `Q ,\ P Q=3c m` and `P R=6c m` . Determine `/_P` and `/_R` .

Explanation

To solve the problem, we will determine the angles \( \angle P \) and \( \angle R \) in triangle \( PQR \), which is right-angled at \( Q \). We know the lengths of the sides: \( PQ = 3 \, \text{cm} \) and \( PR = 6 \, \text{cm} \).

### Step-by-Step Solution:

1. **Identify the sides of the triangle**:
- In triangle \( PQR \), we have:
- \( PQ \) (perpendicular) = 3 cm
- \( PR \) (hypotenuse) = 6 cm
