**Solve the Triangle Using the Law of Sines**

**Problem Statement:**  
Solve the triangle using the Law of Sines. Assume \( a = 6.5 \), \( b = 3.7 \), and \( \angle A = 80^\circ \). Round the length to one decimal place and the angles to the nearest whole number.

**Inputs to be Found:**  
\( c = \) [input box]  
\( \angle B = \) [input box]  
\( \angle C = \) [input box]

**Diagram Explanation:**

The image shows a triangle labeled as \(\triangle ABC\). The sides and angles are labeled as follows:
- Side \( a \) is opposite angle \( A \) and is already given as 6.5.
- Side \( b \) is opposite angle \( B \) and is already given as 3.7.
- Side \( c \) is opposite angle \( C \), and its value is to be determined.
- Angle \( A \) is given as \( 80^\circ \).

In the triangle:
- Point \( A \) marks the vertex of angle \( A \).
- Point \( B \) marks the vertex of angle \( B \).
- Point \( C \) marks the vertex of angle \( C \).

Apply the Law of Sines to find the missing side and angles.
