A 9 foot ladder leans against a building the foot of the ladder is 3 feet away from the building if a 6-foot ladder is propped against the building at the same angle with the ground the foot of the new ladder would be how far away from the building

Respuesta :

Answer:

2 feet

Step-by-step explanation:

We have 2 similar triangles here, so

6 / 9 = x /  3   where x is the distance of the new ladder from the building

x = 6*3 / 9

x = 2 ft answer

Answer:

2'

Step-by-step explanation:

ladder, bldg wall n ground form a triangle

cuz the two ladders are at the same angle

the two triangles are similar

their sides are in the same ratio:

9:6 = 3:x where x is the distance from bldg of the 6' ladder

x=3*6/9

= 2'
