SolutioN :

 \tt \dagger  \:  \:  \:  \:   \: \fbox{Sin \theta =  \dfrac{ \sqrt{3} }{2}}

With know, Sin 60° = √3 / 2.

 \tt  : \implies Sin \theta =  \dfrac{ \sqrt{3} }{2}

 \tt  : \implies Sin \theta =  sin \: 60 \degree

 \tt : \implies \theta = 60 \degree

We have,

  • P = √3.
  • B = ?
  • H = 2.

★ Let's find value of Base ( By Pythagoras theorem )

 \tt  : \implies H^2 = P^2 + B^2.

 \tt : \implies  \big(2 \big)^2 =  \big( \sqrt{3}  \big)^2 + B^2.

 \tt : \implies  4=  3 + B^2.

 \tt : \implies   B^2 = 1.

 \tt : \implies   B =  \sqrt{1}

 \tt : \implies   B =  1.

★ Let's Find Trigonometry Ratio.

  • Sin theta = √3 / 2.
  • Cos theta = 1 / 2.
  • tan theta = √3.
  • Cosec theta = 2 /√3.
  • Sec theta = 2.
  • Cot theta = 1 / √3.

\rule{100}2

VerificatioN :

  • The value of theta = 60° ( Find above )

So,

We are notice,

  • Sin 60° = √3 / 2.
  • Cos 60° = 1 / 2.
  • tan 60° = √3.
  • Cosec 60° = 2 /√3.
  • Sec 60° = 2.
  • Cot 60° = 1 / √3.

Hence Verify.
