Answer:


\huge \boxed{ \boxed{2 + √(3)}}

Step-by-step explanation:

to understand this

you need to know about:

  • trigonometry
  • PEMDAS

given:


  • \frac{1 + \cos( {30}^(o) ) }{1 - \sin( {30}^(o) ) }

tips and formulas:

  • cos(30°)=
    (√(3))/(2)

  • \sin( {30}^(o) ) = (1)/(2)

let's solve:


  1. \sf sustitute \: the \: value \: of \: \sin( {30}^(o) ) and \cos( {30}^(o) ) \\ \sf (1 + ( √(3) )/(2))/(1 - (1)/(2) )

  2. \sf simplify : \\ ( (2 + √(3) )/(2) )/( (1)/(2) )

  3. \sf simplify(fraction) : \\ (2 + √(3) )/(2) / (1)/(2) \\ (2 + √(3) )/(2) * 2 \\ \therefore 2 + √(3)
