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
<h3>Tan(80) = base / height</h3>
Tan(80) = 3172 / x
x = 3172 / Tan(80)
x = 559.31 m
Answer:
The circle is centered at the origin (0,0).
The length of it’s radius is 5.
The equation of the circle is
→(x-0)²+(y-0)²=5²
→<u>x²+y²=25</u>
