Step-by-step explanation:
The value of x in the polygon that has six sides(hexagon) is 14.
What is a hexagon?An hexagon is a polygon with six sides.
The exterior angles of the hexagon are as follows:
80°, 56°, 61°, 43°, 92°, and (2x)°.
Therefore,
sum of exterior angle = 360°
Hence,
80 + 56 + 61 + 43 + 92 + 2x = 360
332 + 2x = 360
2x = 360 - 332
2x = 28
x = 28 / 2
x = 14

Answer:
Answer:
x = (4√3)/3 units
Step-by-step explanation:
Here we have a right 60,30 Triangle with Side 2 units and Htpotenuse x units.
Now, Sin 60° = Opp. /Hyp Sin 60° = 2/x But we know that, Sin 60° = √3/2 So,√3/2 = 2/x Cross multiplying we get,
x√3 = 4x = 4/√3 Rationalizing the denominator, x = (4/√3) × (√3/√3) x = (4√3)/3 units

El área de un rectángulo es 600 cm2 . Calcula las dimensiones del rectángulo sabiendo que su perímetro es 100 metros.
Answer:
Step-by-step explanation:
The area of a rectangle is 600 cm2. Calculate the dimensions of the rectangle knowing that its perimeter is 100 meters.
The formula for the area of a triangle =
Length × Width = 600 cm²
LW = 600
W = 600/L
Perimeter of a rectangle = 2L + 2W = 100m
2L + 2W = 100
we substitute
2L + 2(600/L ) = 100
2L + 1200/L = 100
Multiple all through by L
2L² + 1200 = 100L
2L² - 100L + 1200 = 0
We factorise
2L² - 60L - 40L + 1200= 0
Las dimensiones del rectángulo serían:
Longitud = 30m
Ancho = 20m
Halla el largo y el anchoDado que,
Área del rectángulo = 600[tex]m^2[/tex]
Sabemos,
Área del rectángulo = l × b
entonces,
l × b = 600[tex]m^2[/tex]
⇒ l = 600/b ...(i)
A continuación, tenemos,
Perímetro = 100m
Lo sabemos,
Perímetro del rectángulo = 2(l + b)
⇒ 100 = 2(l + b)
al poner (i), tenemos,
⇒ [tex]100/2 = (600/b + b)[/tex]
⇒ [tex](600 + b^2)/b = 50[/tex]
al resolver esto, obtenemos;
[tex]b^2 + 600 = 50b[/tex]
⇒ [tex]b^2 - 50b + 600 = 0[/tex]
⇒ [tex]b^2 - 30b - 20b + 600= 0[/tex]
⇒ [tex]b(b - 30) - 20(b - 30) = 0[/tex]
⇒ [tex](b - 20) (b - 30)[/tex]
∵ [tex]b = 20 m, b = 30m[/tex]
poniendo el valor de b, podemos encontrar:
[tex]l = 600/20[/tex]
∵ [tex]l = 30 m[/tex]
∵ Longitud = 30m
Ancho = 20m

A tower has lost contact with a GPS satellite. The satellite is at 4500 meters over the Earth at a location 2000 meters from the tower. At what angle should the tower point and scan to make contact again? Note the height of the tower is not included. Round answers to the nearest whole degree.The angle of elevation from the top of the tower to the satellite is?
Answer:
66°
Step-by-step explanation:
It is given that :
Distance of the satellite from the tower = 2000 m
Height of the satellite above the tower = 4500 m
Therefore the angle of elevation can be found out by :
[tex]$\tan \theta = \frac{4500}{2000}$[/tex]
[tex]$\tan \theta = \frac{9}{4}$[/tex]
[tex]$\tan \theta = 2.25$[/tex]
[tex]$\theta = \tan^{-1}(2.25)$[/tex]
[tex]$= 66 ^\circ$[/tex]
Therefore the tower can make contact with GPS satellite when it pointed at 66° angle.
