Find the areas of the sectors formed by ∠DFE. Round your answers to the nearest hundredth.
Answer:
Area of sector DFE = 177.79cm²
Area of sector DGE = 437.65cm²
Step-by-step explanation:
Find the diagram attached;
Area of the sector is expressed according to the formula;
Area of the sector = theta/360 * πr²
theta is the central angle = 360 - 256
theta = 104°
r is the radius = 14cm
Substitute into the formula as shown;
Area of the sector = theta/360 * πr²
Area of the sector DFE = 104/360 * 3.14(14)²
Area of the sector DFE = 0.289 * 615.44
Area of the sector DFE = 177.79cm²
Hence the area of the sector <DFE to the nearest hundredth is 177.79cm²
For sector DGE:
Area of the sector DGE = 256/360 * 3.14(14)²
Area of the sector DGE = 0.7111 * 615.44
Area of the sector DGE = 437.65cm²
Hence the area of the sector <DGE to the nearest hundredth is 437.65cm²

Questions 7 and 8 please. Really need help thank you!!
Answer:
7) sin 60° = 25√3/Z
0.8660 = 25√3/Z
Z = 50
8) using the Pythagorean theorem:
50² = (25√3)² + y²
2500 = 1875 + y²
y² = 625
y = 25
Answer:
z = 50
y = 25
Step-by-step explanation:
Using the 30, 60, 90 triangle rule
you can figure this out.
The rule says
With a 30, 60, 90 triangle
Given the shorter leg, (side across the 30 degree angle,
To find longer leg (side across the 60 degree angle):
Multiple shorter leg by radical 3.
To find hypotenuse (side across the 90 degree angle):
Multiple shorter leg by 2.
Thus
Shorter leg (side opposite 30 degree): 25
Longer leg (side opposite 60 degree):
25 radical 3
Hypotenuse(side opposite 90 degree): 50

Actually Welcome to the concept of Areas,
Let's divide the above map in to 2 parts , that is a rectangle and a triangle, and add both thier areas to get the area of the Nevada.
so we get as,
Area of triangle = 1/2*b*h
Area of triangle ==> 1/2*309*306 ==> 47277 mi^2
Area of rectangle = l*b = 205*309 ==> 63345 mi^2
Area of NEVADA = 47277 + 63345 = 110622 mi^2
hence the area = 110622 mi^2
Answer:
the approximate area of Nevada is 110,567 mi²

Some one help me solve for x
Answer:
x = 10
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Sum the angles and equate to 360
9x + 15 + 85 + 90 + 80 = 360, that is
9x + 270 = 360 ( subtract 270 from both sides )
9x = 90 ( divide both sides by 9 )
x = 10

Look at the work for the following function. What mistake did they make when using the quadratic formula to find the solutions? What are the real solutions to the function?
Answer:
see below
Step-by-step explanation:
whenever there is negative number being squared, you need to add the brackets so that you inside the - 1 in front of the number
so this step is wrong
[tex] \sqrt{ - 9 { }^{2} - 4(1)(20) } [/tex]
the -9 ² , you must include the brackets to include the -1 in front of the 9
so it should be
[tex] \sqrt{( - 9) {}^{2} - 4(1)(20) } [/tex]
so you will get = 1
and then you continue with other parts of the formula and you will get real solutions

What is the solution
Answer:
x=-5
y=-2
Step-by-step explanation:
equation 1 - equation 2
(2x-4y=-2) - (2x+3y=-16) = (-7y=14)
y=14/-7=-2
then substitute y=-2 into any equation

can you figure out the missing number in this sequence?
2, 5, 9, 14, 27
Answer:
The missing number in the sequence is 20
Step-by-step explanation:
The difference between the numbers are as follows: 3,4,5,6,7
The missing number of the given sequence is 13.
The given sequence is,
2, 5, 9, 14, 27
We can see that the difference between each consecutive number is increasing.
The difference between 2 and 5 is 3,
The difference between 5 and 9 is 4,
The difference between 9 and 14 is 5,
And the difference between 14 and 27 is 13.
Therefore, it's possible that the next number in the sequence could have a difference of 14 or more.
So,
To determine the missing number,
We can look at the pattern of the differences between the numbers in the sequence.
Since the difference between 14 and 27 is 13,
We can assume that the difference between the missing number and 27 is at least 14.
Therefore, we can subtract 14 from 27 to get our missing number, which is 13.

The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. The value of x is 6.2 units.
What is Tangent (Tanθ)?The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The base is the adjacent smaller side of the angle θ.
The value of x is,
x = AB - AC
x = 31(Tan 37°) - 31(Tan 29°)
x = 6.17659 ≈ 6.2 units.
Hence, the value of x is 6.2 units.
