Answer:
The height of pole is 20√3 m each and distance of pole from the point on road is 60 m and 20 m respectively.
Step-by-step explanation:
Given:
Two poles of equal heights are standing on opposite side of the road which is 80 m wide facing each other. From a point on the road the angle of elevation of poles are 60° and 30° respectively.To Find:
The height of poles and the distance of that point on the road from the pole.Formula used:
tan60° = √3 tan30° = 1/√3Let the height of each pole be H metres.
Also, let's assume that distance of the point from one pole (as shown in figure) be x m.
According to question, we have
tan60° = H/(80-x)
H = (80-x)√3.... (1)
Also, tan30° = H/x
H = x/√3... (2)
Putting value of eq(2) in eq(1), we get
x/√3 = (80-x)√3
x = 3(80-x)
x = 240 - 3x
4x = 240
x = 60 m
Putting value of x in eq(2), we get
H = 60/√3 = 20√3 m
So, the height of pole is 20√3 m each and distance of pole from the point on road is 60 m and 20 m respectively.
Answer:
Height of Pole: 20√3 m
Distance Of Point From Poles: 20m and 60m
Step-by-step explanation:
The attached graph may help you understand my explanation better
The two poles are Ab and CD and are 80m apart
O is the point between them
The angle of elevation from O to A is 60°
The angle of elevation from O to D is 30°
Since the two poles are given to be of equal height,
AB = CD
In ΔAOB using the law of tangents
tan 60° = AB/BO
tan 60° = √3 and AB = x
So we get
√3 = x/BO
Multiplying both sides by BO we get
√3 · BO = x
or BO = x/√3
Looking at ΔCOD
tan 30° = DC/OC
tan 30° = 1/√3
1/√3 = x/OC
OC · ( 1/√3) = x
OC = x ÷ 1/√3
= x · √3/1
OC = √3x
We also know that BO + OC = 80
Plugging this information with values computed gives us
x/√3 + √3x = 80
Multiply by √3 on both sides
(x/√3) · √3 + (√3x) √3 = 80√3
(x/√3) · √3 = x since the √3 terms cancel out
(√3x) √3 = 3x
So we get
(x/√3) · √3 + (√3x) √3 = 80√3
=>
x + 3x = 80√3
4x = 80√3
x = (80√3)/4
x =20√ 3
So the height of each pole = 20√ 3 m ≈ 34.64 m
The distance OC can be found from the previous equation
OC = √3x
=> OC = √3 x 20√3 = 20 x 3 = 60m
Since BO + OC = 80 m
BO = 80 - 60 = 20 m
Answer:
Height of each pole = 20√3 m
The point is located 20 m from one pole and 60 m from the other pole
James is solving a number puzzple that involves three integers, a,b, and c, where, c is a positive integer.The product of a and b is 6.The product of a and c is -4.The product of b and cis -6.
Answer:
a = -2
b = -3
c = 2
Step-by-step explanation:
a*b = 6 {The product of a and b is 6]
a*c = -4 [The product of a and c is -4]
b*c = -6 [The product of b and c is -6]
- Rearrange:
1) a*c = -4 to a = (-4/c)
2) b*c = -6 to b = (-6/c)
Now substitute:
a*b = 6
(-4/c)*(-6/c) = 6
(24/c^2) = 6
c^2 = (24/6)
c^2 = 4
c = 2
use this value of c to find a and b:
a = (-4/c)
a = (-4/2)
a = -2
b = (-6/c)
b = (-6/2)
b = -3

The value of z in this convex polygon is equal to 66°
What is a polygon?A polygon can be defined as a two-dimensional geometric shape that comprises straight line segments and a finite number of sides.
Note: The number of sides (n) of a pentagon is 5.
In Geometry, the sum of all the interior angles of a polygon with "n" sides is given by this formula:
Interior angle = 180 × (n - 2)
Interior angle = 180 × (5 - 2)
Interior angle = 180 × 3
Interior angle = 540°.
Now, we can determine the value of z as follows:
(180° - 2z) + (180° - z) + 130° + 108° + 140° = 540°
3z - 378° = 540° - 360°
3z = 378° - 180°
3z = 198°
z = 198°/3
z = 66°

Can someone help me understand the following because I’m confused?
Given:
a.) Each small box of paper weighs 50 pounds.
b.) Each large box of paper weighs 80 pounds.
c.) There were 4 more large boxes shipped than small boxes.
d.) The total weight was 1750 pounds.
Since the scenario is involving two types of boxes, we will be using two variables to represent each of them.
Let,
x = the total number of the small box of paper
y = the total number of the large box of paper
Let's now generate the system of equations that we will be using to able to solve the problem.
1st relationship: There were 4 more large boxes shipped than small boxes.
Putting this into equation, we get:
[tex]\text{ y = x + 4}[/tex]2nd relationship: The total weight was 1750 pounds.
For us to get the total weight, we will be adding the sum of the number of each box by the weight each box has.
We get,
[tex]\text{ 50x + 80y = 1750}[/tex]In summary:
Let x = the total number of the small box of paper
Let y = the total number of the large box of paper
System of equations:
a.) y = x + 4
b.) 50x + 80y = 1750
Is this statement true or false?
0 x 5 = 5 x 0
The statement is true. Multiplication is commutative, which means that the order of multiplication does not affect the result.
The statement "0 x 5 = 5 x 0" is true because of the commutative property of multiplication. In multiplication, the order of factors does not change the result.
When we multiply 0 by 5, it equals 0 since anything multiplied by 0 is 0. Similarly, when we multiply 5 by 0, the result is still 0. Both expressions are equal to 0, confirming the commutative property.
In summary, 0 x 5 and 5 x 0 are interchangeable and yield the same result, proving the truth of the statement based on the fundamental property of multiplication.

How to find the angle of a triangle?The angle of a triangle can be found using sine rule.
Therefore, applying sine rule,
a / sin A = b / sin B = c / sin C
Hence,
5 / sin x = 6.9 / sin 88°
cross multiply
5 sin 88° = 6.9 sin x
5 × 0.99939082701 = 6.9 sin x
4.9969541351 = 6.9 sin x
divide both sides by 6.9
sin x = 4.9969541351 / 6.9
sin x = 0.72419625146

What is defined as the anti derivative?Derivatives are the inverse of antiderivatives. An antiderivative is a function that does the opposite of what a derivative does. There are many antiderivatives of one function, but they all take the shape of a function + an arbitrary constant. Indefinite integrals rely heavily on antiderivatives.An antiderivative, F, of the a function, f, is a function that may be differentiated to get the original function, f. In other words, an antiderivative is defined mathematically as follows: ∫ f(x) dx = F(x) + C, where C is the integration constant.The given function is; eˣ².
To find the anti derivative of the function, integrate the function with respect to x.
Let y = eˣ²
Integration of exponential function remains same but applying the chain rule, the derivative of the power of exponent comes at the denominator.
∫y. dx = ∫eˣ² .dx.
∫eˣ² .dx. = eˣ²/(d/dx)x²

AM = 5x
5(2) = 10
AM = 10

(assuming AH = HM = MS)
7 + 7 +7 = x
21 = x
AM = 14
I hope this helps!
the overall change in temperature when the temperature is 10 degrees fahrenheit at 9:00 am and 10 degrees fahrenheit at 6:00 pm.
The change in temperature based on the time and the temperature given is 0.
What is temperature?It should be noted that temperature simply means the degree of coldness and hotness of a particular body.
In this case, we want to calculate the overall change in temperature when the temperature is 10 degrees fahrenheit at 9:00 am and 10 degrees fahrenheit at 6:00 pm.
Therefore, the change will be the subtraction of the values given. This will be:
= 10°F - 10°F
= 0
