Ответ:
Option C) 1727.6 m
Step-by-step explanation:
Given that the angle of depression from D to F measures 10°.
Also given that DE =300 m.
Since 10 is angle of depression, we can visualize a right triangle with hypotenuse DF=300 m and EF, DE two legs.
In the right triangle DEF, the angle opposite 10 is the side DE![\frac{DF}{DE} =\frac{hypotenuse}{opposite side}= cosec 10\\\\DF =300 cosec 10 = 1727.6 m](/tpl/images/0147/2134/538d9.png)
