Question

At a particular time when the sun's altitude is 30 degrees the length of the shadow on a vertical tower is 45m.calculate the length of the shadow of the same tower when the suns altitude is 45 degrees.

Answer 1

Step-by-step explanation:

Let the length of the tower be h m. Hence the length of the tower is 25.98 m (ii) Let the length of the shadow be x m. Hence the length of the shadow is 25.98 m Hence the length of the shadow is 15 Read more on Sarthaks.com - https://www.sarthaks.com/163034/at-particular-time-when-the-suns-altitude-30-the-length-the-shadow-of-vertical-tower-is-45

Answer 2

The length of shadow of the same tower is 67.5 m when the sun altitude is 45 degrees.

Step-by-step explanation:

Since we have given that

Angle = 30 degrees

Length of shadow = 45 m

Angle = 45 degrees

Then, we need to find the length of shadow.

Since there is direct relation:

So, it becomes,

$\dfrac{30}{45}=\dfrac{45}{x}\\\\30x=45\times 45\\\\30x=2025\\\\x=\dfrac{2025}{30}\\\\x=67.5\ m$

Hence, the length of shadow of the same tower is 67.5 m when the sun altitude is 45 degrees.
