An eagle 311 feet in the air spots its prey on the ground. The angle of depression to its prey is 15°. What is the distance between the eagle and its prey? Round to the nearest foot.​

Answers

I think the answer is 1,161 feet

Sorry if that’s incorrect, but here’s the explanation in case you need it:

The tangent of a triangle is the opposite leg over the adjacent leg. 311 is the opposite leg, and X would be the adjacent leg. So 311 divided by x is equal to tan 15. If we rearrange this to be equal to X, X equals 311 divided by tan 15. Tan 15 is equal to 0.2679, so 311/0.2679 = 1,160.6. That amount rounds up to 1,161, giving you the answer of 1,161 feet.

Review the graph of function h(x).
What is lim h(x), if it exists?

Answers

Answer:

0

Step-by-step explanation:

because you have to look at what both sides of the graph is doing as it approaches 2.

from the left, we can see the the graph is going down All the way to 0 at x=2.

and from the right side, the graph is going up to 0 at x=2.

therefore the graph is approaching 0.

The limit of h(x) as x tends to 2 is equal to 0.

How to get the limit of h(x) when x tend to 2?

Remember that a limit is not the same as an evaluation, the limit studies the behavior of the function near the value, not in x = 2.

While we can see that h(2) = 3 (we have a jump there). We can see that around x = 2 the function tends to zero.

From that, we conclude that:

[tex]\lim_{x \to \ 2} h(x) = 0.[/tex]

Then the correct option is the first one.

Answers

Answer: c=35

D=90

E=55

Step-by-step explanation:

Since d is a right angle it is 90. Take 90 and subtract it from 180 to get 90.Set them equal to 90 so 3x+11+5x+15=90

Simplify

8x+26=90

8x=64

X=8

Now take x and plug it in for each equation

3(8)+11=35

5(8)+15=55

So measured of c is 35

Measure of e is 55

And d is 90

cos²x - sin²x = 0,66​

Answers

x = 24.35°

Step-by-step explanation:

Recall that

cos²x - sin²x = cos 2x

which means that

cos 2x = 0.66 ---> 2x = cos^-1 (0.66) = 48.7°

or x = 24.35°

Answer:

x = 24.35, 155.65, 204.35, 335.65  degrees ( for 0 < x < 360 degrees).

Step-by-step explanation:

cos²x - sin²x = 0.66

cos^2 x = 1 - sin^2 x so

1 - sin^2 x - sin^2 x = 0.66

1 - 2sin^2 x = 0.66

2sin^2 x = 1 - 0.66

sin^2x = 0.34/2 = 0.17

sin x = +/- √0.17

= +/- 0.41231

x = 24.35 degrees ( in first quadrant)

and 180 + 24.35 = 204.35 degrees in third quadrant.

Step-by-step explanation:

Answer:

4000

Step-by-step explanation:

because the 200+200 are in parenthesis that shows that you will need to do it first.

so.. 200+200=400

and now the second part is asking for the square root of 100. We know that 10 times 10 is 100. This means that 10 is the square root of 100.

And for our last step they ask to multiply our two answers.

so 400 x 10= 4000
