Question

line AB = 5 centimeters, and line BC = squarroot 200 centimeters, what is the length of line segment AC

Answer 1

diagram ?

Answer 2

use Pythagorean theorem

Answer 3

use the pythagorean theorem :
AC^2 = AB^2 + BC^2
AC^2 = 5^2 + (sqrt(200))^2
AC^2 = 25 + 200
AC^2 = 225
so, AC = sqrt(225) = ...

Answer 4

so what would the length of AC be?
