## IAmCreature 3 years ago If someone could please help!!! I need someone to explain how to find the answer! A 15-ft ladder leans against a wall. The bottom of the ladder is 4 ft from the wall. The bottom is pulled out 3 ft farther. How much does the top end move down the wall?

2. akkib89

the ladder will always make 90 degree so apply pythgoras therom for both cases

3. nubeer

|dw:1350903085367:dw| 3 feet more away then before makes 7 feet.. just apply pythagoerous

4. nubeer

|dw:1350903264425:dw| find the value of x in both cases.. and subtract them that will tell u hpw much the ladder have moved down.

5. akkib89

first one will give you the the height of the ladder against the wall under root 209 which is appx 14.4568 2nd case will give you height 13.266 difference is 1.19 wchich is the ans (appx 1.2)

@akkib89 thats nice of u to give out answer.. but this is a learning site not a solution site.. here its prefer to guide the person to the answer rather then solving for them.
