    7.5 m

    Step-by-step explanation:

    The angle of depression from the bird to the fish is 15°

    The height of the bird is 2m

    The distance the bird must fly be directly above the fish is?

    Model your sketch as a right triangle with height 2m and angle 15°. The distance to find is the leg distance the bird has to cover to be directly above the fish

    Apply the formula for tan of Ф

    Tan Ф=opposite:adjacent

    Tan Ф=O/A

    Tan 15°=2/A

    0.26794919243=2/A

    A=2:0.26794919243

    A=7.46

    A=7.5 m
