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
Answer:
35.7037 feet (rounded up to four decimal places)
Step-by-step explanation:
The shadow the tree makes with the ground is 25 feet.
The angle of elevation from the ground to the top of the tree is 55°
The height of the tree and its shadow meet at 90°
Height(h) of the tree ÷ length of the shadow = tan 55°
i.e = tan 55°
h = 25 × tan 55° = 35.70370017
Or height (h) of the tree is 35.7037 feet (rounded up to four decimal places)
