A ship is 7 ft from the dock. One sailor who is standing at the front of the boat 10 ft above dock level tosses rope to another sailor who is standing on the dock to tie the boat to the dock. How is the angle of elevation for the sailor standing on the dock related to the angle of depression for the sailor standing at the front of the boat?
Answer:
ım not speak english because i'm turkish
The angle of the depression is equal to the angle of elevation for the same place.
The angle of elevation for the sailor standing on the dock is equal to the angle of depression for the sailor standing at the front of the boat which is 55 degrees.
What is angle of elevation?The angle of elevation is the angle between the horizontal line and the line of sight which is above the horizontal line.
What is angle of depression?The angle of depression is the angle between the horizontal line and the line of sight which is below the horizontal line.
Given information-
The distance between the ship and dock is 7 ft.
The one sailor is standing 10 ft above the dock level.
The another sailor is standing on the dock.
The angle of depression and elevation is shown in the image.
Here the angle made by the sailor who is 10 ft above from the dock level on the ship is,
[tex]\tan \theta=\dfrac{10}{7}[/tex]
Find the value of angle as,
[tex]\theta=\tan ^-(\dfrac{10}{7})\\\theta=55[/tex]
Hence the angle of depression is 55 degree.
As the angle of the depression is equal to the angle of depression for the same place.
Thus the angle of elevation is 55 degrees.
Hence, The angle of elevation for the sailor standing on the dock is equal to the angle of depression for the sailor standing at the front of the boat which is 55 degrees.

tree, and 2 more apples fell. What fraction of the apples are still
on the tree
HELP PLS!
Answer:
13/18
Step-by-step explanation:
There were 18 apples. Namid ate 3 and more 2 fell:
3+2=5
So, rested 18-5=13 apples. The total was 18, and rested 13, so the fraction is 13/18

You start driving west for 8 miles, turn left, and drive south for another 11 miles. At the end of driving, what is your straight line distance from your starting point? Round to the nearest tenth of a mile.
Using Pythagorean's theorem we can see that the distance is 13.6 miles.
How to find the distance to the starting point?You can think of this as a right triangle.
The two distances that you drive are the legs of it, and the distance betwen the initial point and the final point is the hypotenuse of the triangle.
Then we can use Pythagorean's theorem to find the hypotenuse, we know that:
H^2 = A^2 + B^2
H = √(A^2 + B^2)
Where:
A = 8 miles.
B = 11 miles
REplacing that we will get:
H = √( (8mi)^2 + (11mi)^2)
H = 13.6 miles.

A carton contains a dozen eggs, of which 3 contains no yolk. If 3 eggs are chosen at random for a cake, what is the probability that they all have no yolk?
Answer:
25%
Step-by-step explanation:
[tex]\frac{3}{12}[/tex] x 100 = 25%
A carton contains a dozen eggs, of which 3 contain no yolk. If 3 eggs are chosen then the probability that they all have no yolk is 3/12
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes

what is the area of the unshaded path
Answer:
114 feet
Step-by-step explanation:
the black and white will both have the same area. and given that each path is 1 ft wide and initially 12 ft long we can slowly determine the area.
x times 1 will still equal x
12(1) still equals 12 so we can just write it as 12.
12+12+11+11+10+10+9+9+8+8+7+7= 114
where I came up with this? there are a total of 12 sides if you follow the black path. and by every 2 sides the path gets shorter by 1 foot.
the white side also has 12 sides if you look. therefore both the black and the white part of the shape will have an area of 114.

Dado que sen =9/10 y cos =8/10, encuentre los valores restantes de las cuatro funciones trigonométricas.
Answer:
tgα = 9/8
secα = 10/8
cscα = 10/9
ctgα = 8/9
Step-by-step explanation:
PAra resolver esto, es necesario conocer como se determinan las funciones trigonométricas en general. Ya tenemos el valor del seno y coseno de un angulo dado (supongamos un angulo α)
Si senα = 9/10 y cosα = 8/10, para calcular la tangente se aplica la siguiente expresión:
tgα = senα / cosα (1)
Reemplazando tenemos:
tgα = (9/10) / (8/10) Aqui se simplifican los 10, y nos queda
tgα = 9/8Nos quedan 3 funciones, y son las inversas de estas 3 funciones anteriores, y se determinan de la siguiente forma:
secα = 1 / cosα (2)
cscα = 1 / senα (3)
ctgα = 1 / tgα = cscα / secα (4)
Aplicando estas 3 expresiones tenemos:
secα = 1 / (8/10) Se aplica inversión de numerador y denominador
secα = 10/8cscα = 1 / (9/10)
cscα = 10/9ctgα = 1 / (9/8)
ctgα = 8/9Espero te sirva
Which statement about 214° is correct?
O A. tan 214° < 0
O B. sin 214° < 0
O C. cos 214° > 0
Answer:
B.
Step-by-step explanation:
214 degree terminates in the 3rd quadrant.
Sine and cosines are both negative there.
This means that sin(214)<0 and cos(214)<0.
If sine and cosine are both negative and since tangent is the quotient of them, then tangent is positive, or tan(214)>0.

Two mechanics worked on a car. The first mechanic worked for 10 hours, and the second mechanic worked for 15 hours. Together they charged a total of $2475 . What was the rate charged per hour by each mechanic if the sum of the two rates was $200 per hour?
Answer:
1st: 105/h
2nd: 95/h
Step-by-step explanation:
10A+15B=2475 (1)
A+B=200 |*10 => 10A+10B=2000 (2)
From (1) - (2), we have 5B=475, so B=95
then A+95=200 so A is 105
A bag contains 5 green marbles, 7 yellow marbles, 4 blue marbles, 6 pink marbles, and 3 purple marbles. If two marbles are chosen without replacement, find the probability of choosing a yellow marble, then another yellow marble. Give your answer as a fraction in simplest form.
Answer:
The probability of choosing a yellow marble then choosing another one without replacement is 1/30.
Step-by-step explanation:
First, get the total amount of marbles.
5 + 7 + 4 + 6 + 3 = 25 total marbles.
Now find the probability of finding a yellow marble.
P = 5 yellow marbles / 25 total marbles.
Now find the probability of finding a yellow marble after pulling one without replacement.
P = 4 yellow marbles / 24 total marbles.
To find the probability of both events happening, multiply the probabilities together.
(5/25) * (4/24)
Multiply the numerators and denominators.
