1-cosx/1+cosx=secx-1/secx+1 Verify the identity. I tried all identities that I could, but could not find how it worked. Can you show me how to verify with all steps?

I usually do not ask on but I've tried everything else and still got nothing.
Currently in Algebra 2 and in the 9th grade.

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
