Answer 2

Answer:

• Length of Shadow = 10 m.

Step-by-step explanation:

Given:

• Height of tower = 10 m
• Sun's angle of elevation = 45°

To Find:

• Length of Shadow.

Let length of Shadow be 'L' meter.

Now, we know that

=> tan Θ = Height of tower/Length of Shadow

Now, we know the value of tan 45° = 1.

Put the values,

=> tan 45° = 10/L

=> 1 = 10/L

=> L = 10 m

Hence, Length of Shadow = 10 m.
