The value of the internal angle m from the heptagon is given by the equation m = 141°.
What is the sum of a polygon's internal angles?The formula returns the sum of the internal angles of a polygon.
The sum of the internal angles of an n-sided polygon is n = 180° (n - 2), where n is the number of sides = angle in degrees
Given the data,
Let's call the polygon a heptagon.
The polygon has n sides, which equals 7 sides.
Now, n = 180 is the sum of the interior angles of a polygon with n sides ( n - 2 )
7θ = 180 ( 7 - 2 )
7θ = 180 ( 5 )
When we simplify the equation, we obtain 7 = 900°.
A = 900° denotes the sum of the internal angles of the polygon.
And , the value of A = 120° + m° + 148° + 90° + 142° + 130° + 129°
900° = m + 759°
Subtracting 759° on both sides of the equation , we get
m = 141°
Hence , the interior angle ∠B = 141°

An object is moving east, and it’s velocity changes from 65 m/s to 25 m/s in 10 seconds.which describes acceleration
Answers
Answer:
The acceleration of object is -4 ms⁻²
Step-by-step explanation:
We are given:
Initial Velocity = 65 m/s
Final Velocity = 25 m/s
Time t = 10 seconds
We need to find acceleration.
The formula used to find acceleration is: [tex]Acceleration=\frac{Final\:Velocity-Initial\:Velocity}{Time}[/tex]
Putting value in the formula and finding acceleration:
[tex]Acceleration=\frac{Final\:Velocity-Initial\:Velocity}{Time}\\Acceleration=\frac{25-65}{10}\\Acceleration=\frac{-40}{10}\\Acceleration=-4\:ms^{-2}[/tex]
So, acceleration of object is -4 ms⁻²

What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Your friend wants to buy a pair of jeans that are on sale for 30% off if the jean's original price is $40.
Let "S" be the price of sales. Then the equation is given as,
30% = [($40 - S) / $40] x 100
0.30 = ($40 - S) / $40
S = $40 - $12
S = $28
The price of the pair of jeans that are on sale for 30% off will be $28.

5х - 18 = 10x - 3
Answers
Step-by-step explanation:
if we add 18 to both side then it becomes 5x=10x+15 and if we divide by five, x=2x+3
Because you add 18 to both sides therefore -18+18=0 and -3+18=15
So you get 5x+10x=15
After that combine like terms which is 5x+10x=15x
You get 15x=15
Finally x=1
