They are similar.

Reason: In triangle BCD the angles are 69° and 58°, so the third angle is 180° − 69° − 58° = 53°. In triangle EFG the angles are 69° and 53°, so the third angle is 180° − 69° − 53° = 58°. Thus the two triangles have the same three angle measures (69°, 58°, 53°), so they are similar by the Angle-Angle (AA) criterion.
