Since triangles GHI and LKJ are similar (denoted by the symbol ~), their corresponding angles are equal. Therefore, the angles of triangle LKJ can be determined by using the angles of triangle GHI.

Given:
- \( m\angle G = 30^\circ \)
- \( m\angle H = 80^\circ \)
- \( m\angle I = 70^\circ \)

The angles of triangle LKJ, which correspond to the angles of triangle GHI, will be:
- \( m\angle L = m\angle G = 30^\circ \)
- \( m\angle K = m\angle H = 80^\circ \)
- \( m\angle J = m\angle I = 70^\circ \)

However, you specified that the angles J and L cannot be 30°, 70°, or 80°. Since the triangles are similar, the only way to find the actual measures for angles J and L, without overlapping with the measures from triangle GHI, is to restructure how the angles match up.

To solve for the angle measures that must add up to 180° within triangle LKJ, we can utilize the fact that the sum of angles in any triangle is always \( 180^\circ \).

Given that:
- \( J + K + L = 180^\circ \)

Using the previously found measure:
- \( K = 80^\circ \)

We can express the relationship:
- \( J + L + 80^\circ = 180^\circ \)

From that, we can reorganize it:
- \( J + L = 180^\circ - 80^\circ \)
- \( J + L = 100^\circ \)

The angles \( J \) and \( L \) must be two measures that add up to \( 100^\circ \) and cannot include \( 30^\circ \), \( 70^\circ \), or \( 80^\circ \). Therefore, you could have:
- \( J = 40^\circ \) and \( L = 60^\circ \)
or
- \( J = 60^\circ \) and \( L = 40^\circ \)

In conclusion, the measurements can be:
- \( m\angle J = 40^\circ, m\angle K = 80^\circ, m\angle L = 60^\circ \)
or
- \( m\angle J = 60^\circ, m\angle K = 80^\circ, m\angle L = 40^\circ \).
