Find measure of one exterior angle in each regular polygon
Answer:
Pentagon = 72°
Octagon = 45°
Step-by-step explanation:
To solve for the measure of one exterior angle in a regular pentagon;
n = number of sides
180 - (180 x n-2/n)
180 - (180 x 5-2/5)
180 - (180 x 3/5)
180 - (540/5)
180 - 108
Exterior angle = 72°
To solve for the measure of one exterior angle in a regular octagon;
n = number of sides
180 - (180 x n-2/n)
180 - (180 x 8-2/8)
180 - (180 x 6/8)
180 - (1080/8)
180 - 135
Exterior angle = 45°
Find the slope of the line that passes through (-26, 9) and (32, 71).
Answer:
[tex]Slope = \frac{31}{29}[/tex]
Step-by-step explanation:
Step 1: Define the slope formula
[tex]Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Step 2: Find the slope
[tex]Slope = \frac{71-9}{32-(-26)}[/tex]
[tex]Slope = \frac{62}{58}[/tex]
[tex]Slope = \frac{31}{29}[/tex]
Answer: [tex]Slope = \frac{31}{29}[/tex]

Find the measure of the indicated angle to the nearest degree.
Answer:
Step-by-step explanation:
Adjacent to the undetermined angle is 6, and the hypotenuse has been given. We can conclude, after looking at our SOHCAHTOA, that we will be using cosine(CAH) to solve this problem.
Let the unspecified angle be [tex]\theta\\[/tex] (This sign is called theta, which is just a sign for angle)
Lets start!
cos[tex]\theta\\[/tex] = adj/hyp
cos[tex]\theta\\[/tex] = 6/13
[tex]\theta\\[/tex] = [tex]cos^{-1}[/tex](6/13)
[tex]\theta\\[/tex] = 62.5
[tex]\theta\\[/tex] = 63

Find the value of x in each case:
Please help me
It's an easy 40 points if you answer this
Answer:
x = 45
Step-by-step explanation:
The angles labeled with the pink x are the same. Line V and Line X are parallel and alternate interior angles are equal when the lines are parallel.
We know the 3 angles inside the triangle and the sum of the angles of a triangle are 180
x+x+ 2x = 180
4x= 180
4x/4 = 180/4
x = 45
For g(x) = x - 2 find the value of x for which g(x) = -4.
Answer:
x=-2
Step-by-step explanation:
g(x) = x-2
Let g(x) = -4
-4 =x-2
Add 2 to each side
-4+2 = x-2+2
-2 = x
Answer:
x = -2
Step-by-step explanation:
g(x) = -4
g(x) = x - 2
-4 = x - 2
+2 +2
-2 = -x

Trong một lớp học có tỉ số học sinh nam và nữ là 7: 5.Tìm số học sinh của lớp biết số học sinh nam lớn hơn số học sinh nữ là 6 học sinh
Answer:
Học sinh nam là 21 học sinh, số học sinh nữ là 15 học sinhH
Step-by-step explanation:
Tỉ số giữa nam và nữ là x/y = 7/5 => x/7 = y/5
áp dụng tính chất của dãy tỉ số bằng nhau, ta được:
x/7 = y/5 => x-y =/7-5 = 6/2 = 3
Vì x/7 = 3 => x = 21
y/5 = 3 => y= 15
Vậy số học sinh nam là 21 học sinh, số học sinh nữ là 15 học sinh

Answer:
135
Step-by-step explanation:
Multiply 2 1/4 by 3/4 by 1 1/4 to get 2 7/64.
Then, multiply 1/4 by 1/4 by 1/4 to get 1/64.
Then divide 2 7/64 by 1/64 to get 135.

3x-4y;x=4andy=3 evaluate the expression for the indicated values of the variables
Step-by-step explanation:
In this problem, all we have to do is replace x and y with the values we've been given.
It can be helpful to think of 3x as 3 * x (which is the same exact thing), so I'll write it out that way.
3*x - 4*y
(replace)
3*4 - 4*3
(multiply (doing this step first because of PEMDAS))
12 - 12
(subtract)
0
Answer:
0
Answer: 0
Step-by-step explanation:
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
Given
3x - 4y
x = 4, y = 3
Substitute value of x and y
3(4) - 4(3)
Simplify multiplication
12 - 12
Final subtraction
0

Height is 2ft. More than its width. If the total area is 99ft squared , determine the dimensions of the painting.
Answer: [tex]9\times 11\ ft^2[/tex]
Step-by-step explanation:
Given
Height is [tex]2\ ft[/tex] more than its width
Suppose the width is [tex]x[/tex]. So, height becomes [tex]x+2[/tex]
Area of the painting is [tex]99\ ft^2[/tex]
Area is the product of width and height
[tex]\therefore 99=x(x+2)\\\Rightarrow 99=x^2+2x\\\Rightarrow x^2+2x-99=0\\\Rightarrow x^2+11x-9x-99=0\\\Rightarrow (x+11)(x-9)=0\\\Rightarrow x=-11,9[/tex]
Neglect the negative values
[tex]\text{Width =}9\ ft\\\text{height =}9+2=11\ ft[/tex]

| the British 50-pence coin shown on the right is in the shape of a
regular heptagon. Determine the measure of one interior angle.
Show your work.
For a regular polygon with n sides, interior angle
= [(n-2) × 180°]/n
So, interior angle of this regular heptagon shape
= [(7 - 2) × 180°]/7
= (5 × 180°)/7
= 900°/7
= (900/7)°
= 128.571° [approximately]
Answer:
hello,
Step-by-step explanation:
center angle : 360°/7 °
half interior angle=0.5*(180-360/7)=900/14=450/7 = 64 ° +2/7° ≈64.3 °
interior angle= 128°+4/7°≈128.6 °
