To find the angle of the helicopter, we are going to take advantage of the fact the the sum of the interior angles of a triangle is always 180°. Lets denote that angle with

, so:




Look what we have here: a angle of 90°, so our triangle is a right triangle.
Now, let

be the distance between Amanda and the helicopter. Using the law of sines:

Remember that sine of 90 ° is equal to 1, so:



We can conclude that the distance between Amanda and the helicopter is
2000 feet.
Answer:
13
Step-by-step explanation:
Given the equation h(x) = 2x²
To solve for h(-2) + 5 then, we need to break the problem into two parts
First, we will solve for the function h(x) at x = -2
h(x) = 2x² so
h(-2) = 2(-2)²
h(-2) = 8
Knowing this, we can plug 8 into our original expression for h(-2)
8 + 5
This gives us 13
The first number is 15. The 2nd number is 30 cuz it’s double the first. The third number is 18 less than 30 so it is 12. They all add up to 57. Third # = 12
