Answer 1

Answer:

$\large{❒}$$\large\sf\fbox\pink{Required Answer :}$

• Let the (x,0) some expressed coordinate of the point x.
• Now, we have to find x of the distance from (x,0) to (1,3) is expressed as the same Distance from (x,0) to (1,2)

${\color{Yellow}{\fbox{\textsf{\textbf{We use,}}}}}$

$\bold{❒}$$\sf\fbox\blue{Distance formula :}$

$\large\purple{⟹}$$\boxed{d = \sqrt{x²-x}²+(y²-y)²}$

$\bold{❒}$$\sf\fbox\blue{According to the distance formula,}$

${\color{Yellow}{\fbox{\textsf{\textbf{we have,}}}}}$

➪$✓{(x-(-1))² + (0-2)²=}$

➪ (x-1)² + (0-3)² = (x+1))² + (0-2)²

➪ x² - 2x + 1 + 9 = x² + 2x + 1 + 4

➪ -2x + 10 = 2x + 5

➪ 4x = 5

➪ x = ${\frac{5}{4} }$

$\bold{❒}$$\sf\fbox\blue{Therefore,}$
