Question

Find the distance between (7,15) and (1,7).

Answer 1

In order to find the distance between two points we will use the next formula

`d=\sqrt[]{\mleft(x_2-x_1\mright)^(2)+\mleft(y_2-y_1_{}\mright)^(2)}`

where

(7,15)=(x1,y1)

(1,7)=(x2,y2)

we substitute the values

`d=\sqrt[]{(1-7)^2+(7-15)^2}`
`d=\sqrt[]{6^2+8^2}=\sqrt[]{100}=10`

The distance between (7,15) and (1,7) is 10
