The foot of a ladder is placed 7 meters from a wall. if the top of the ladder rests 9 meters up on the wall, how long is the ladder?

The ladder is 11 m long approximately .

Step-by-step explanation:

Given :The foot of a ladder is placed 7 meters from a wall.

To Find :If the top of the ladder rests 9 meters up on the wall, how long is the ladder?

Solution :

The foot of a ladder is placed 7 meters from a wall.

Base = 7 m

The top of the ladder rests 9 meters up on the wall

So, height at which ladder touches wall i.e. perpendicular = 9 m

We are supposed to find how long is the ladder i.e. Hypotenuse

Hence The ladder is 11 m long approximately .

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
