Find the number of sides (n) of the polygons with the angle values shown in the items below.
a) The sum of the interior angles is 10,440∘
b) The value of each interior angle is 171∘
As per the concept of polygon,
a) The sum of the interior angles is 10,440° then the number of sides is 58
b) The value of each interior angle is 171°, then the number of sides is 36
A polygon is a two-dimensional geometric shape made up of straight lines and angles. The number of sides a polygon has is directly related to the sum of its interior angles.
a), we can use the formula for the sum of the interior angles of a polygon, which is (n-2) times 180 degrees, where n is the number of sides. To find n, we can rearrange the formula to
=> n = (sum of interior angles / 180) + 2.
Plugging in the value of 10,440 degrees for the sum of interior angles, we get
=> n = (10440 / 180) + 2 = 58.
Therefore, the polygon in item a) has 58 sides.
For item b), we can use the formula for the value of each interior angle of a regular polygon, we get
=> n = (180(n-2)) / 171 = (180n - 360) / 171.
Solving for n, we find that the polygon in item b) has 36 sides.
In conclusion, polygons with the angle values shown in items a) and b) have 58 and 36 sides respectively. These formulas can be applied to any polygon to find the number of sides based on its interior angle values.

Give the circumference and the area of a circle with diameter 4yd use the value of 3.14 for pi
Answer:
Circumference = 12.56 yd
Area = 12.56 yd²
Step-by-step explanation:
Equations we need to know:
Circumference of circle - 2πr
Area of circle - πr²
1) Circumference
2 x 3.14 x 2 = 12.56
2) Area
3.14 x 2² = 12.56
We have to make sure the we are using the radius and not the diameter otherwise our answer would be wrong
Hope this helps, have a lovely day! :)
Answer:
Area=12.56yd^2, Circumfrence=12.56yd
Step-by-step explanation:
the formula for the area of a circle is pi*r^2 and since pi is 3.14 and r is 2 so r^2 is 4 and 4*3.14 is 12.56 (r is the radius)
the formula for the circumference of a circle os 2*pi*r and r is 2 so its 2*3.14*2 multiplying all these terms again gives us 12.56 but be careful with the units as with the area comes yd^2 and with the circumference comes yd only

The triangle on the left is a 45 45 90 triangle and the triangle on the right is a 30 60 90 triangle.
In a 45 45 90 triangle, the length of the hypotenuse is equal to the length of either one of the legs times the square root of 2. So that means that a and c are both 18.
In a 30 60 90 triangle, the length of the hypotenuse is twice that of the leg opposite the 30 degree angle. So that means that b is 36. The length of the leg opposite the 60 degree angle is the length of the other leg times the sq root of 3. So that would give you d = 18 sq root 3.

4n = 48
n = 6
The equivalent equations are 52 = 8n + 4, 4(2n + 1) = 52 and 4 = 52 – 8n.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
To determine which equations are equivalent to each other, we can simplify and manipulate each equation to see if they have the same solution(s).
52 = 8n + 4 can be simplified by subtracting 4 from both sides:
48 = 8n
n=6
Now 4(2n + 1) = 52
8n+4=52
8n=48
n=6
So the 52 = 8n + 4 and 4(2n + 1) = 52 are equivalent equations.
Now 4 = 52 – 8n
8n=52-4 is also equivalent equation.
4n=48 and n=6 are also equal but they are not in the same form as above equations.
Hence, 52 = 8n + 4, 4(2n + 1) = 52 and 4 = 52 – 8n are equivalent equations.

The average speed that Patrick used to run from his home to a shop and walk back to his home is 1.33 m per second.
What is the average speed?The average speed is the total distance divided by the total time.
The average or mean is the quotient of the total value and the total time or number of items in a data set.
The distance from Patrick's home to a shop = 400 m
Running speed from home to the shop = 2 m per second
The total time used in running to the shop = 200 seconds (400/2)
The distance from the shop to Patrick's home = 400 m
Walking speed from shop to the home = 1 m per second
The total time used in walking back to the home = 400 seconds (400/1)
The total distance to and from shop = 800 m (400 x 2)
The total time used to run to and walk from the shop = 600 seconds (200 + 400)
The average speed for the whole journey = Total Distance/Total Time
= 800/600 = 1.33 m per second
