Question

If sec A + tan A = x, then tan A =​

Answer 1

Answer:

Tan A = x - sec A

Explanation:

please mark me as brainliest

Answer 2

secA+tanA= x....(1)

=> 1/ (secA- tan A ) x as (secA+ tan A )

( sec A - tan A ) = sec² A tan ² A=1

=> sec A - tan A =1/x …(2)

subtraction Eqn. (2) from eqn (1)

2 tan A = x -1/x

=> tan A (1/2) (x -1/x).
