A life guard is sitting on a platform, looking down at a swimmer in the water. If the lifeguards line of sight is 8 feet above the ground and the angle of depression is 18 degrees, how far away is the swimmer from the lifeguard? Round to the nearest tenth
Answers
Answer: The swimmer is 26 ft (approximately) away from the lifeguard
Step-by-step explanation: Please refer you the attached diagram.
The lifeguard sitting on the platform is labeled as point P, and the swimmer down below is at point S. The point G is the point directly beneath the lifeguard. So, we have a right angled triangle PSG. Also the angle of depression is 18 degrees, so the angle of sight between the lifeguard and the ground is 72 degrees (that is, 90 - 18 = 72).
Having derived a right angled triangle with two sides and a reference angle, we can now use the trigonometric ratio which is;
CosP = Adjacent/Hypotenuse
The adjacent is the side that lies between the reference angle and the right angle (side PG), while the hypotenuse is the side facing the right angle (side PS). Hence;
Cos72 = 8/g
By cross multiplication we now have
g = 8/Cos72
g = 8/0.3090
g = 25.8899
Approximately, g = 26 ft.

please would you be so kind and help me with problems four through 12?
Answers
I will do 4 and 5 only. Also, post one problem at a time.
Question 4
Measure of arc GJ = measure of the central angle, which in this case is 90 degrees. So, the measure of arc GJ = 90°.
Question 5
The measure of diameter HJ = 180 degrees.
We need to find the adjacent angle which I will call angle x.
So, x = 180° - 151° = 29 degrees.
Just like Question 4 above, the measure of 29 degrees is the central angle for arc HI.
As you know, HI = the measure of the central angle. So, the measure of arc HI = 29°.
Try the rest on your own.
As you do the rest, keep in mind that the measure of a circle in terms of degrees is 360 degrees. This will help you do the rest of the questions for circle B.

Answers
Answer:
58 degrees
Step-by-step explanation:
We know that angles on a straight add up to 180 degrees. Therefore:
To find the angle at the top of the triangle do 180-112 = 68
To find the angle at the right side of the triangle do 180 - 126 = 54
We know that angles in a triangle add up to 180 degrees. Therefore:
To find m do 180 - (54 + 68) = 58

30. From 55 lb to 24 lb
Answers
Answer:
Decease in weight by 56.4%
Step-by-step explanation:
From 55 lb to 24 lb,
There is a decrease in the weight from 55 lb to 24 lb.
For the percentage decrease in weight,
Change in weight = 55 - 24
= 31 lb
Percentage change in weight = [tex]\frac{\text{Total change}}{\text{Initial value}}\times 100[/tex]
= [tex]\frac{31}{55}\times 100[/tex]
= 56.36%
≈ 56.4%
Therefore, there is a decease in weight by 56.4%.

A-2
B-3
C-4
D-5
Answers
Answer:
B. 3
Step-by-step explanation:
Let's make an equation for this. Our unknown number is x.
x
We are adding 4.
x + 4
Then multiplying by 5.
(x + 4) • 5
It will equal 35.
(x + 4) • 5 = 35
To solve this, divide both sides by 5.
(x + 4) = 7
Now subtract 4 from both sides.
x = 3
This is your answer.
Check this by plugging it back into our original equation.
(x + 4) • 5 = 35
(3 + 4) • 5 = 35
7 • 5 = 35
35 = 35
Your answer is correct.

Answers
Answer: sqrt(61)
Step-by-step explanation:
For parts a) and c1), refer to the attached picture.
For part b), the distance formula is:
d = sqrt[(x2 - x1)^2 + (y2 - y1)^2]
Using x1 = -1, y1 = -4, x2 = -6, y2 = 2:
d = sqrt[(-6 + 1)^2 + (2 + 4)^2] = sqrt[25 + 36] = sqrt(61)
Part c2) Another way to find the length of AB without using the distance formula is by drawing the line and measuring it according to the scale.
Part d) This will only work as long as the graph paper is accurately made, and the scale computation is done correctly. However, this will only give approximations, and will not give an exact answer when radicals are involved.
