Answer:
21.27 meters.
Step-by-step explanation:
Please find the attachment.
Let H and h represent height of building and tree respectively.
We have been given that a person on the ground looks up at an angle of 28° and sees the top of a tree and the top of a building aligned. The tree is 20 m away from the person and the building is 60 m away from the person.
We know that tangent relates opposite side of a right triangle with its adjacent side.





Similarly, we can find height of the tree.






Therefore, the difference in heights between the building and tree is 21.27 meters.

Answer:
Choice A: 0.4
Step-by-step explanation:
We are given the the equation that relates the height and width by a constant:

Therefore

From the points given on the graph we find

or

So the constant is 0.4.
