#BAL #AnswerWithQuality

Step-by-step explanation:

 \frac{1 -  {tan}^{2}60 }{1 +  {tan}^{2}60 }  = cosx \\  =  >  \frac{1 - 3}{1 + 3}  = cosx \\  =  >   \frac{ - 2}{2} = cosx \\  =  >  - 1 = cosx \\  =  > cos(180) = cosx \\ =  > x = 180

[tan 60° = √3] and [-1 = cos 180°]

_____________________________

log[(secA + tanA)(secA - tanA)]

= log[sec²A - tan²A]. [ (a +b)(a-b) = a²-b²]

= log1. [ log 1 = 0]

= 0
