From the top of the tower 30 m height a man is observing the base of a tree at an angle of depression measuring 30 degree. Find the distance between the tree and the tower.
Please show your work
Answer:
30√3 m ≈ 52 m
Step-by-step explanation:
The side ratios in a 30°-60°-90° triangle are 1 : √3 : 2. The long leg of the triangle is √3 times 30 m, or about 51.96 m.
The distance between the tree and the tower is about 30√3 m ≈ 52 m.
__
If you haven't memorized the ratios of this special triangle, you can use the relation ...
Tan = Opposite/Adjacent
tan(30°) = 30/d
d = 30/tan(30°) = 30√3 = 51.96 . . . . same as above

Diagram :-
[tex]\setlength{\unitlength}{1mm}\begin{picture}(5,5)\thicklines\multiput(-0.5,-1)(26,0){2}{\line(0,1){40}}\multiput(12.5,-1)(0,3.2){13}{\line(0,1){1.6}}\multiput(12.5,-1)(0,40){2}{\multiput(0,0)(2,0){7}{\line(1,0){1}}}\multiput(0,0)(0,40){2}{\qbezier(1,0)(12,3)(24,0)\qbezier(1,0)(-2,-1)(1,-2)\qbezier(24,0)(27,-1)(24,-2)\qbezier(1,-2)(12,-5)(24,-2)}\multiput(18,2)(0,32){2}{\sf{5 \: m}}\put(9,17.5){\sf{12 \: m}}\end{picture}[/tex]
Solution :-
As per provided information in the given question, we have been given that the Radius of a cylinder is 5 meters. The height of a cylinder is 12 meters. We have been asked to find the volume of a cylinder.
To calculate the volume of a cylinder, we will apply the formula below :-
[tex] \bigstar \: \: \: \boxed{ \sf{ \: \: Volume_{(Cylinder)} = \pi r^2 h \: \: }}[/tex]
Substitute the given values into the above formula and solve for Volume :-
[tex]\sf:\implies Volume_{(Cylinder)} = \pi r^2 h[/tex]
[tex]\sf:\implies Volume_{(Cylinder)} = (3.14)(5 \: m)^2(12 \: m)[/tex]
[tex]\sf:\implies Volume_{(Cylinder)} = (3.14)(25 \:m^2)(12 \: m)[/tex]
[tex]\sf:\implies Volume_{(Cylinder)} = (78.5 \:m^2)(12 \:m)[/tex]
[tex]\sf:\implies\bold{Volume_{(Cylinder)} = 942 \: m^3}[/tex]
Therefore :-
The volume of a cylinder is 942 m³.[tex]\\[/tex]

Answer:
1.a: 6x = y
1.b: 7 packs
Step-by-step explanation:
1.a: there are 6 cups per can so if you multiply it for each can, you get the cups.
1.b: there are 16 cups per gallon. Packs of 4 cans so in total, there are 24 cups in total. So there are 1.5 gallons per pack. 1.5x6 = 90 so that's no enough. 1.5x7 = 10.5. That's more than enough but she can't split the pack so she needs to buy 7 packs.
how do i solve? the help video doesnt actually help
Answer:
y = 5x - 8
Step-by-step explanation:
The linear equation in slope intercept form :
y = mx + c
m = slope ; c = intercept
m = Rise / Run = (y2 - y1) / (x2 - x 1)
Rise = (y2 - y1) = (12 - (-8)) = (12 + 8) = 20
Run = (x2 - x1) = (4 - 0) = 4
Slope, m = Rise / Run = 20 /4 = 5
Hence,
y = 5x + c
For the points ; y = 12 ; x = 4 ; we could obtain c
12 = 5(4) + c
12 = 20 + c
12 - 20 = c
-8 = c
The equation becomes :
y = 5x - 8
Miles read 4 books in the first half of March. By the end of March, the library had added Miles to the top-readers board for reading more than 10 books in a month.Let x represent how many books Miles read in the second half of March. Which inequality describes the problem?
Answer:
[tex]x>6[/tex]
Here, [tex]x[/tex] denotes number of books read by Miles in the second half of March
Step-by-step explanation:
Given: Miles read 4 books in the first half of March.
Also, Miles read more than 10 books in a month.
[tex]x[/tex] denotes number of books read by Miles in the second half of March.
To find: inequality that describes the problem.
Solution:
Total number of books read in month of March = Number of books read by Miles in the first half of March + Number of books read by Miles in the second half of March = [tex]4+x[/tex]
Also, Miles read more than 10 books in a month.
Therefore,
[tex]4+x>10\\x>10-4\\x>6[/tex]
