You need a ladder that will reach up 25 foot tall hose when place 10 feet away from the house how the tall does the ladder need to be

26.9 foot long ladder at least (probably better make it 27 feet to be safe)

Step-by-step explanation:

This is a Pythagorean theorem question

The ladder is the hypotenuse or c

the distance from the wall is a leg or a

and the wall is the other leg or b

a² + b² = c²

10² + 25² = c²

100  + 625 = c²

           725 = c²

         √        √

          √725 = √c²

            26.9  = c

step-by-step explanation:

times by times

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
