It is not possible to answer the question because BES and GES are not even defined!

Yes, triangles FGH and JKL are similar. The similarity can be established using the Angle-Angle (AA) postulate, which states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar. If the angles of FGH correspond to the angles of JKL, the triangles are indeed similar.
