Answer:
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have the following equation given in the problem above:
2. Apply the Distributive property:
4. Now, you must add like terms:
5. Solve for , then the result is:
Height of building =60 feet (where woman is trapped)
distance of bottom of ladder from base of building = 40 feet
This makes a right angled triangle as shown in figure.
here hypotenuse =length of ladder
base = distance of bottom of ladder from base of building = 40 feet
perpendicular =Height of building =60 feet (where woman is trapped)
So here we can use Pythagoras theorem to find the length of ladder.
Hypotenuse² = base² + perpendicular²
height of ladder = √(60² +(40)² = √3600 +1600 = √5200
height of ladder = 72.1 feet
