Two of the interior angles of a polygon are 134° and 156° and each of the remaining angles is 151°. Find the number of sides of the polygon.
The number of sides of a polygon with interior angles of 134° and 156° and each of the remaining angles as 151° is 12 sides.
Polygons
The sum of the exterior angles of a polygon is 360°. For regular polygons the exterior angles are the same (congruent).
Therefore,
Interior angle + exterior angle = 180°
Therefore,
156 + x = 180
x = 180 - 156
x = 24°
134 + y = 180
y = 180 - 134
y = 46°
180 - 151 = z
z = 29°
sum of exterior angle = 360 degrees.
Therefore,
360 - 46 - 24 = 290°
Then,
290 / 29 = 10
The number of sides = 10 + 2 = 12 sides

Use the following compound interest formula to complete the problem. a = p (1 startfraction r over n endfraction) superscript n superscript t sandra has two credit cards, p and q. card p has a balance of $726.19 and an interest rate of 10.19%, compounded semiannually. card q has a balance of $855.20 and an interest rate of 8.63%, compounded monthly. assuming that sandra makes no purchases and no payments with either card, after four years, which card’s balance will have increased by more, and how much greater will that increase be? a. card q’s balance increased by $7.22 more than card p’s balance. b. card q’s balance increased by $6.69 more than card p’s balance. c. card p’s balance increased by $3.43 more than card q’s balance. d. card p’s balance increased by $0.80 more than card q’s balance. please select the best answer from the choices provided a b c d
The difference between the amount in two cards of Sandra after 4 years will be $125.58 approx.
How to find the compound interest?If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:
[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]
For this case, Sandra has got 2 credit cards p and q. Calculating the final amount both card will have after 4 years:
Case 1: For card p:Initial amount = p = $726.19
The rate of interest is r = 10.19% = 10.19/100 = 0.1019 (converted percent to decimal)
Years for which amount is compounded = 4 years, Thus, t = 4
The interest is compounding semiannually, that means twice per year, thus, n = 2
Thus, the final amount in card p after 4 years would be:
[tex]a = p(1 + \dfrac{r}{n})^{nt}\\\\a = 726.19(1+0.1019/2)^{2 \times 4} \\\\a= 726.19 \times (1.05095)^8 \approx 1080.70\: \rm (in \: dollars)[/tex]
Case 2: For card q:Initial amount = p = $855.20
The rate of interest is r = 8.63% = 8.63/100 = 0.0863 (converted percent to decimal)
Years for which amount is compounded = 4 years, Thus, t = 4
The interest is compounding monthly, that means twelve times per year, thus, n = 12
Thus, the final amount in card q after 4 years would be:
[tex]a = p(1 + \dfrac{r}{n})^{nt}\\\\a = 855.20(1+0.0863/12)^{12 \times 4} \\\\a= 855.20\times (1.0071916)^{48} \approx 1206.28\: \rm (in \: dollars)[/tex]
Clearly card q has more amount than card p at the end of 4 years.
The difference is: 1206.28 - 1080.70 = 125.58 (in dollars)

Answer/Explanation:
The formula for a rectangular prism is Length x Width x Height
With this information we can multiply 6x8x2 and get 96 ft³.
This is the volume of the original prism.
Doubling the dimensions means multiplying each side by 2.
The new dimensions would be a.16 b.4 c.12
Use the formula to find volume. 12x16x4=768
The volume of the enlarged prism is 768 feet³
For bonus question, divide 768 by 96.
The scale factor is 8.

y = - x + - 2
Step-by-step explanation:
Using the equation y = mx + b, find the m (slope) from the graph and the b (y-intercept from the graph). The slope, m, is the rise over the run from point A to point B. The rise is -5 and the run is 5. [tex]\frac{-5}{5}[/tex] = -1. The y-intercept, b, is the point the graph passes through the y-axis. The b is -2 so y = -x+-2.

what is the value or x?
10.4

61.6
92
Answer:
x = 10.4
Step-by-step explanation:
This is a supplementary apple which means the angle is equal to 180 degrees. You do 180 - 128 which equals 52. Then you divide 52 by 5 to figure out "x". 52 divided by 5 equals 10.4. So x = 10.4.
To make sure, you can plug in "x" as 10.4. (5 * 10.4) equals 52. 52 + 128 equals 180.
Answer:
52
Step-by-step explanation:
180-128=52
the whole angle is 180

Additional comment
If you draw a line from F to D you get a triangle FED that perfectly matches the space ABC. Moving ∆FED to fill ∆ABC transforms the figure into a rectangle that is 5 cm high and 6 cm wide. Its area is (5 cm)(6 cm) = 30 cm².

In the figure below, k || l and m || n. Find the values of y and x.
Answer:
x = 30
y = 115
Step-by-step explanation:
Suppose line m is parallel to line n:
65+y = 180 because they are supplementary angles
subtract 65 from both sides
y = 115
angle represented by y and the angle represented by 3x + 25 are alternate angles and their measure is equal, so to find the value of x we can write the following equation:
3x + 25 = 115 subtract 25 from both sides
3x = 90 divide both sides by 3
x = 30
