Question

find height of flagpole please​

Answer 1

Answer: 1/3 of 100 feet

Step-by-step explanation: The man's height: 6 ft tall is the whole and the shadow: 4 ft tall are the parts 4 this means the fraction from this logic is 4/6 = 2/3. 2/3 of 50 = 33.33333333333333333 Infinite or 1/3 of 100 ft.

Answer 2

$\sf\huge{\underline{Question :}}$

A man 6 feet tall casts a shadow 2 ft long, at same time, a flag pole casts shadow which is 50ft long, how tall is flag pole?

$\sf\huge{\underline{Answer :}}$

Previous Knowledge Req. :

• At a time Sun is at One position so the angle of elevation made by different object with shadow, is same for all the objects.
• Similarity on triangles.

1. AA criteria
2. Same Ratio of Sides property

Given :

Two triangles{if we objectify the condition given}

sides 6,4 and H,50

Triangles are Similar— our deduction made from given condition.

To Find :

H, height of the Flag Pole

Solution :

Let H be the height of the Flag Pole

Both triangles are similar, using AA{or AAA} criteria

Height of both Thing are in the same ratio as of their shadows. {property of similar triangles}

$\dfrac{6}{4} = \dfrac{H}{50}$

$\longrightarrow H = \dfrac{3}{2} \times 50$

$\longrightarrow H = 75 ft$
