your question is wrong ... it should be
sin48°sec42°+cos48°cosec42°
Solution:
LHS
sin48°sec42° + cosec42°
sin(90°-42°)sec42° + cos(90°-42°)cosec42°
cos42°sec42°+sin42°cosec42° = 1+1 = 2 = RHS {Proved}
sin48°sec42°+cos48°cosec42°
Solution:
LHS
sin48°sec42° + cosec42°
sin(90°-42°)sec42° + cos(90°-42°)cosec42°
cos42°sec42°+sin42°cosec42° = 1+1 = 2 = RHS {Proved}
