Question

If (1,x) is at √10 units from (0,0) then x is
Plz help me with this​

Answer 1

Answer:

Step-by-step explanation:

By using distance formula:

Distance= √(x2-x2)^2+(y1-y2)^2

We know, dist=√10 units..

So,

√10= √1^2+x^2

Square on both sides,

10= x2+1

X=3 or -3.....

Answer 2

let x1 = 0, y1 = 0

and x2 = 1 , y2 = x

distance = √10

we know that distance between two points is

distance = √[(x2-x1)²+(y2-y1)²]

√10 = √[(1-0)²+(x-0)²]

squaring on both sides

10 = 1²+x²

x² = 9

x = ±9
