To determine the correct similarity statement, we need to analyze the given angles of the two triangles.
For triangle \( \triangle GHJ \):
- \( m∠G = 118° \)
- \( m∠H = 25° \)
- \( m∠J = 37° \)
For triangle \( \triangle ACB \):
- \( m∠A = 118° \)
- \( m∠C = 25° \)
- \( m∠B = 37° \)
Since both triangles have the same angle measures, they are similar because the corresponding angles are equal.
The correct statement describing their similarity is:
\[ \triangle GHJ \sim \triangle ACB \]
Thus, the answer is: \(\triangle GHJ \sim \triangle ACB\)
