The problem in the image appears to involve solving a geometric problem related to a triangle, where different values for angles and lengths are given.

Let's analyze the text more closely:

1. **Triangle ABC** with a few points and angles provided:
   - \( m(\widehat{ABC}) = 57^\circ \)
   - \( m(\widehat{BCA}) = 34^\circ \)
   - \( BD = 14 \)
   - \( BD = 14 \), \( CD = 10 \), \( AB = AD = 18 \), \( \text{calculate BC} \).

It seems like we're dealing with some triangle properties and applying the triangle's rules to find side lengths or angles. I can assist with breaking down the solution step-by-step. Here's how we could approach it:

1. **Use the Angle-Sum Property** to calculate \( m(\widehat{A}) \).
2. **Apply the Law of Sines or Cosines** to solve for the unknown sides or angles.
3. **Make use of any given side relationships or special properties** in the triangle configuration.

Would you like me to guide you through these steps more explicitly or give a detailed solution?

Given the triangle ABC, where m(angle B) = 57 degrees, m(angle C) = 34 degrees, BD = 14, CD = 10, AD = 18, calculate BC.
