Two squared plus nine squared plus nine squared is going to be equal to our hypotenuse square which Im just calling C is going to be equal to C squared which is really the distance. We have a right-angled triangle we know the lengths of the two shorter sides and we want to find out the length of the hypotenuse. 10 10 15 15 so 100 225 which equals 325.
Then find the vertical distance between the points by subtracting 12 from 3 which is -9.
The distance formula is derived from the Pythagorean theorem. 1 25 1 25. Calculate the distances between two points using the distance formula. Using the distance formula shown in the above article find the horizontal distance between the two points by subtracting -8 from 2 which is 10.
