Question

sec A + tan A = x find sec A ​

Answer 1

Your answer is in the attachment

Answer 2

Answer:

Step-by-step explanation:

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

1/cosA+sinA/cosA= x

x=1+sinA/cosA.........(2)

Substitute (2) in (1)

SecA+tanA=1+sinA/cosA

SecA= 1+sinA/cosA-tanA

SecA=1+sinA/cosA-sinA/cosA

SecA=1+sinA-sinA/cosA

SecA=1+0/cosA

SecA=1/cosA
