Question

The height of a tower is 10 m. What is the length of its shadow when Sun's altitude is 45°?

Answer 1

Answer:

The length of the shadow is 10 m .

Step-by-step explanation:

Given :  Height of the tower, AB = 10 m.

Sun's altitude, θ = 45°

Let the Length of the shadow , BC = x m .

In right angle ∆ ABC ,  

tan θ = P/B  

tan 45° = AB/BC

1 = 10/x

x = 10 m  

Hence, the length of the shadow is 10 m .

Answer 2

done, answer of ques is 10m hope this help ☺️

by applying tan45 =1

10/x=1

x=10m
