dangina [55]

the height of the tree is 23 feet .

<u>Step-by-step explanation:</u>

Here we have , Tony is 5.75 feet tall. Late one afternoon, his shadow was 8 feet long. At the same time, the shadow of a nearby tree was 32 feet long. We need to find Find the height of the tree. Let's find out:

According to question , Tony is 5.75 feet tall. Late one afternoon, his shadow was 8 feet long . Let the angle made between Tony height and his shadow be x . Now , At the same time, the shadow of a nearby tree was 32 feet long. Since the tree is nearby so tree will subtend equal angle of x. Let height of tree be y , So

⇒ Tanx=\frac{y}{32}

But , From tony scenario

⇒ Tanx=\frac{5.75}{8}

Equating both we get :

⇒ \frac{y}{32}  = \frac{5.75}{8}

⇒ y=\frac{5.75(32)}{8}

⇒ y=23ft

Therefore , the height of the tree is 23 feet .
