Answer: yes it should be C
We have a right angled triangle here so we can use trigonometry. Let the distance between Amanda and the helicopter be x , then:-
cos 60 = x / 4000
x = 4000 * cos 60
= 4000 * 1/2
= 2000 feet Answer

Answer:
f(h(x)) = 2x - 4
General Formulas and Concepts:
<u>Algebra I</u>
- Composite Functions
- Combining Like Terms
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = x - 7
h(x) = 2x + 3
f(h(x)) is x = h(x)
<u>Step 2: Find f(h(x))</u>
- Substitute: f(h(x)) = (2x + 3) - 7
- Combine like terms: f(h(x)) = 2x - 4
Step-by-step explanation:
we use the law of sine :
sin(A)/a = sin(B)/b = sin(C)/c
with the related angles being opposite of the lines.
so, we have
sin(A)/1 = sin(A) = sin(90)/ sqrt(10) = 1/ sqrt(10) =
= 0.316227766...
cos²(A) + sin²(A) = 1
cos(A) = sqrt(1 - sin²(A)) = sqrt(1 - 0.1)) = sqrt(0.9) =
= 0.948683298...
tan(A) = sin(A)/cos(A) = 0.333333333...
cot(A) = 1/tan(A) = 3
sec(A) = 1/cos(A) = 1.054092553...
csc(A) = 1/sin(A) = 3.16227766...
