i have no idea what to do please help it was due on friday please please help

Answer:
sin Z = 4/5
sin C = 24/25
cos A= 4/5
tan Z = 4/3
Step-by-step explanation:
sin Z = O/H
sin Z = 36/45 = 4/5
sin Z = 4/5
sin C = O/H
sin C = 48/50 = 24/25
sin C = 24/25
cos A = A/H
cos A = 40/50 = 4/5
cos A= 4/5
tan Z = O/A
tan Z = 24/18 = 4/3
tan Z = 4/3
