Question

Find the distance of the point $(6,8)$ and the origin.

Answer 1

As we know that

Distance between two points $(x_1,y_1),(x_2,y_2)$ is $\sqrt{(x_2-x_1{)}^2+(y_2-y_1{)}^2}$ units

Distance between the point $(6,8)$ and origin is $\sqrt{(6-0{)}^2+(8-0{)}^2}=\sqrt{36+64}=\sqrt{100}=10$ units
