Answer:

x = 559.31 m

Step-by-step explanation:

Given in the question,

horizontal distance from airplane to the coral reef = 3172 m

outer angle of depression = 10°

inner angle of depression = 90 - 10

                                           = 80°

It is a question of right angle triangle, we will use trigonometry identity to solve the question

Tan(80) = base / height

Tan(80) = 3172 / x

x = 3172 / Tan(80)

x = 559.31 m
