tan² A = 3(sec A - 1)
Sec²A-1 = 3(sec A - 1)
(sec A - 1)(sec A + 1)=3(sec A - 1)
[(sec A - 1)(sec A + 1)] /(sec A - 1) = 3
sec A + 1 =3
SecA = 3-1
SecA = 2
A = 45
Sec²A-1 = 3(sec A - 1)
(sec A - 1)(sec A + 1)=3(sec A - 1)
[(sec A - 1)(sec A + 1)] /(sec A - 1) = 3
sec A + 1 =3
SecA = 3-1
SecA = 2
A = 45
