Asubmersible traveling at a depth of 250 feet dives at an angle of 15 degrees with respect to a
line parallel to the water's surface. it travels a horizontal distance of 1500 feet during the dive.
what is the depth of the submersible after the dive?

Step-by-step explanation:

The submersible is diving at a down angle of 15° along the hypotenuse AC of triangle ABC.  

Its horizontal track along the surface AB is 1500 ft.

The submersible was already at a depth of 250 feet when it began the dive.

New depth = 250 + 402 = 652 ft

from the sentence, "tomorrow morning, akiko will arrive an hour late" depicts a third person perspective because it doesn't use any pronoun to replace akiko, the subject of the sentence, and it is in singular form since akiko is only one person.
