Answer:

  AB ≈ 581.6 ft

Step-by-step explanation:

The triangle from point A to the base of the lighthouse to the light beam can be modeled as a right triangle with the side opposite the angle being given. That means the distance from A to the base of the lighthouse is found from the tangent relation:

  Tan = Opposite/Adjacent

  tan(7°) = (105 ft)/A

  A = (105 ft)/tan(7°)

Using similar reasoning, the distance to B is ...

  B = (105 ft)/tan(21°)

Then the distance from A to B is ...

  AB = (105 ft)/tan(7°) -(105 ft)/(tan(21°)) = (105 ft)(1/tan(7°) -1/tan(21°))

  AB ≈ 581.6 ft

_____

Additional comment

We know that 1/tan(7°) = cot(7°) = tan(83°). This means the relation can be written ...

  AB = (105 ft)(tan(83°) -tan(69°))

Let the present age of son be x

Therefore,

Present age of the father will be

[tex]\bold{ = 3x\:\: years }[/tex]

9 years ago,

The age of the son was

[tex]\bold{ = ( x - 9)\: years}[/tex]

Age of the father was

[tex]\bold{ = 3(x - 9) \:years ...eq(1)}[/tex]

But,

From eq(1) and eq(2) :-

[tex]\sf{3(x - 9) = 4(x - 9)}[/tex]

[tex]\sf{3x - 27 = 4x - 36}[/tex]

[tex]\sf{3x - 4x = -36 + 27}[/tex]

[tex]\sf{-x = -9 }[/tex]

[tex]\bold{\pink{ x = 9 \: years }}[/tex]

Thus, The present age of the son is 9 years

Age of the father will be

[tex]\sf{ = 3 × 9 }[/tex]

[tex]\bold{\red{ = 27 \: years }}[/tex]

Hence, The present ages of son and father is 9 years and 27 years

Answer:

2x³ - 2x² - 1 + (6 / x² + x + 2)

Answer:

x= 6

y= 2

Step-by-step explanation:

conversion factor is 2, so you have to divide by 2 in order to get your answers :)

Answer:

x = 6

y = 2

Step-by-step explanation:

Just divide 6 a number and you have to get 3, in this case it's 2.

So then divide 4 and 12 by 2, and that will get you the answer.

On solving the linear system, for the value of y = 15, the value of x is 200. The correct option is D.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

The linear equation is shown below.

[tex]\rm \dfrac{1}{5}x - \dfrac{2}{3}y = 30[/tex]

The equation can be written as

[tex]\rm 3x - 10y = 450\\[/tex]

For y = 15, the value of x will be.

[tex]\begin{aligned} \rm 3x - 10*15 &= 450\\\\\rm 3x - 150 &= 450 \\\\\rm 3x &= 600\\\\\rm x &= 200\\\end{aligned}[/tex]

The value of x is 200.

Thus, option D is correct.

Answer:

dang i had a hard time on this wish i could help

Step-by-step explanation:

Given :-

To Find :-

Solution :-

The given system of equation is ,

[tex]\begin{cases} 3x + 2y = 9\dots (i) \\\\ y = 4x + 10 \dots (ii)\end{cases}[/tex]

Firstly , taking equation (ii) ,

[tex] y = 4x +10[/tex]

On subtracting y on both sides, we have ;

[tex] 4x - y +10 = 0[/tex]

Multiplying both sides by 2 ,

[tex] 2(4x -y+10)=2(0)[/tex]

Simplify,

[tex] 8x - 2y = -20 \dots (iii)[/tex]

Adding equation (i) and (iii) ,

[tex] 3x + 2y + 8x - 2y = -20+9[/tex]

Add and subtract the like terms ,

[tex] 11x = -11 [/tex]

Divide both sides by 11 ,

[tex] x = -1 [/tex]

Now substitute this value in equation (i) ,

[tex] 3(-1) + 2y = 9\\ \\ -3 + 2y = 9 \\\\ 2y = 9+3 \\\\ 2y = 12 \\\\ y =\dfrac{12}{2}\\\\ y = 6[/tex]

Hence the correct option is 4 (-1,6) .

I hope this helps . Let me know if you need any further clarification .

Answer:

x = 5 , y = 15

Step-by-step explanation:

Since the figures are congruent then corresponding sides and angles are congruent , that is

WG = DG ( substitute values )

3x - 5 = 10 ( add 5 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

and

∠ WGF = ∠ DGF , that is

15x + y = 90 ( substitute x = 5 )

15(5) + y = 90

75 + y = 90 ( subtract 75 from both sides )

y = 15

The regular octagon has eight equal sides. Then the area of the regular octagon of side length be 4.6 is 102 ft².

It is a polygon that has eight equal sides. In a regular octagon, the opposite sides are parallel. And its diagonals are also equal and intersect at mid-point.

Given

A regular octagon has a radius of 6 ft and a side length of 4.6 ft.

We know the formula for the regular octagon.

Area of the regular octagon = 2(1 + [tex]\sqrt{2}[/tex]) a²

Where a be the side of a regular octagon.

Then the area of the regular octagon will be.

[tex]\rm Area = 2 (1+\sqrt{2} ) a^2\\\\Area = 2*(1 + 1.414) *4.6^2\\\\Area = 2 * (2.414)* 21.16\\\\Area = 102.16[/tex]

Thus, the area of the regular octagon of side length be 4.6 is 102 ft².

(The top and bottom)

A trapezoid has two bases and two legs. As seen, the lengths that represent the bases of the trapezoid are the parallel sides 8 and 6. This is because they go on straight and never intersect each other, which makes them parallel. The length that represents the height of the trapezoid is 4, which is the straight line that connects both bases.
