Which is the angle of elevation from the submarine to the boat? <1, <2 ,<4 <3

grigory [225]

Answer:

Step-by-step explanation:

When an observer is at the same level with the submarine, his line of sight above the horizontal upward to the boat would form an angle called the angle of elevation.

Thus, the angle of elevation from the submarine to the boat is marked as <1. <1 is the angle of elevation from the submarine.
