Answer:
1
Step-by-step explanation:
cos 74°/sin 16°+sin 11°/cos 79°-cos 15°cosec 75°
cos 74°/cos (90-16)°+sin 11°/sin(90-79)°-cos 15°*1/sin 75°
cos 74°/cos 74°+sin 11°/sin11°-cos 15°*1/cos 15°
1+1-1=1

Hello Mate! Here is your answer:
= cos 74°/sin 16° + sin 11°/cos 79° - cos 15°cosec 75°
= cos (90-16)°/sin 16° + sin (90-11)°/cos 79° - cos 15°cosec (90-15)°
= sin 16°/sin 16° + cos 79°/cos 79° - cos 15°sec 15°
= 1+1+1
= 3
I hope this helps.
