Answer:

Given,

secx-tanx=4.....(i)

We know that

sec²x-tan²x=1

(secx-tanx)(secx+tanx)=1

4(secx+tanx)=1

So secx+tanx=(1/4).....(ii)

Adding equation (i) and (ii),

We get

2secx=4+(1/4)

or 2secx=(17/4)

or secx=(17/8)

or cosx=(8/17)

Hope it helps you

If anyone satisfy on my answer then give me thanks. plz
