Answer:
100
Step-by-step explanation:
200+3qq+400+q3q

Answer:

Step-by-step explanation:
Given that,
The height of the tree, h = 14 ft
The height of the shadow, b = 16 ft
We need to find the angle of elevation of the sun from the ground. Let the angle be θ. We can use trigonometry to find it. So,

So, the required angle of elevation of the sun is equal to
.
