Hey I need help please

Scottie = 30

Lighthouse = ? (can't see height in image)

The boat = 0

The fish = -10

Distance between Scottie and fish = 40

Reason:

It starts off by saying that Scottie is 30 meters above, so that is solved. Then it says a height for the lighthouse, which I cant see, but I would figure it out if shown. If a boat is in an ocean or sea, it's always on sea level, which is 0. The fish is 10 meters below sea level, or 0, making it -10. If you add on to -10, where the fish is, until it gets to 30, where Scottie is, you get 40 meters of distance.

21/58.

hope to be marked brainliest
