Question :

 \\

Q) A policeman and a thief are equidistant from a jewel box. Upon considering jewel box as origin, the position of Policeman is (0,5) . If the ordinate of the position of thief is zero, then write the coordinates of the position of thief.

 \\

Answer :

 \\

» Consider the attachment.

» In the attachment,

  • P represents the Policeman.

  • J represents the Jewel Box.

  • T represents the Thief.

 \\

\frak{\underline{\dag\; Given:}}

 \\

  • PJ = TJ (Since they are equidistant)

  • Coordinates of J = (0,0)

  • Coordinates of P = (0,5)

  • Ordinate of T = 0

 \\

\frak{\underline{\dag\;To\:Find:}}

 \\

  • The Coordinates of point T.

 \\

\frak{\underline{\dag\;Solution:}}

 \\

» Since the points are equidistant so, the distance PJ would be equal to the distance TJ.

» We can find the distance between two points using the Distance Formula.

 \\

 \odot \:  \boxed{ \tt d =  \sqrt{(x _{2} - x _{1} ) {}^{2}  +  {(y _{2} - y _{1})  }^{2}  } }

 \\

Finding the distance PJ

 \\

For PJ,

  • \sf x_1=0, y_1=5 &

  • \sf x_2=0, y_2= 0

So,

\colon\rarr\sf\: PJ=\sqrt{(0-0)^2+(0-5)^2}\\\\\sf\colon\rarr\: PJ=\sqrt{0+(-5)^2}\\\\\sf\colon\rarr\: PJ=\sqrt{25}\\\\\colon\dashrightarrow\boxed{\pink{\frak{PJ=5\:units}}}

  \\

Finding the distance TJ

 \\

For TJ,

  • \sf x_1=a, y_1=0

  • \sf x_2=0, y_2=0

So,

\colon\sf\rarr\: TJ=\sqrt{(0-a)^2+(0-0)^2}\\\\\sf\colon\rarr\: TJ = \sqrt{(-a)^2+0}\\\\\sf\colon\rarr\:TJ=\sqrt{a^2}\\\\\colon\dashrightarrow\boxed{\pink{\frak{TJ=a\:units}}}

 \\

Equating PJ & TJ

 \\

\colon\implies\sf\: PJ=TJ \\\\\sf\colon\dashrightarrow\boxed{\red{\frak{a=5}}}

 \\

  • T = ( a,0 ) = ( 5,0 )

 \\

\therefore\;\underline{\sf Coordinates\:of\:the\:position\:of\:the\:Thief=\bf{(5, 0) .}}\\

 \\
