 Betty:

If you need to evaluate the tension / compression loads in red circled truss sections - LN, LK, and EK you first need to develop a free body diagram showing the effective loads at the nodes - E, L, N, and K.

Once you have done that you can calculate the forces in each of the various members. Remember the various truss member must be in pure tension or compression.

Hint - the 105 Load at H is a red herring.
