Answer:
no need to do so many things mentioned in the above given Answer by snehaa. follow my steps below ↓
Step-by-step explanation:
given : tan∅ + sec∅ or sec∅+tan∅ = 8
therefore, we know , sec²∅ - tan²∅ = 1
=> (sec∅+tan∅)(sec∅-tan∅) = 1
=> ( 8 )( sec∅-tan∅ ) = 1
=> sec∅-tan∅ = 1/8
Answer = 1/8
hope it helped .
thanks
brainly please!!
