The area of a shape is the amount of space it occupies
The complete statement is: First, break the irregular polygon into shapes whose area you can find using familiar formulas. The sum of these areas is the area of the polygon.
How to determine the area of an irregular polygonAn irregular polygon contains several familiar shapes.
So, the first thing to do is to break the polygon into smaller shapes
Then calculate the areas of these shapes
Lastly, add the areas of the shapes to get the area of the irregular polygon
Hence, the area of an irregular polygon is the sum of the areas of the shapes that make up the irregular polygon

Which fact helps you prove the isosceles triangle theorem, which states that the base angles of any isosceles triangle have equal measure?
1. The base angles of an equilateral triangle have equal measure
2. if two sides of a triangle are equal, the third side must be equal to the others
3.If a triangle is equiangular, then it is equilateral.
4.If one angle of a triangle is larger than another angle, then the side opposite the larger angle is longer than the side opposite the smaller angle.
Answer:
4. If one angle of a triangle is larger than another angle, then the side opposite the larger angle is longer than the side opposite the smaller angle.
Step-by-step explanation:
Facts about equiangular/equilateral triangles have little bearing on isosceles triangles.
The one relevant fact from the given list is that larger angles are opposite longer sides. This requires you to conclude that equal angles are opposite equal sides, which is the conclusion of the isosceles triangle theorem.

Sambriddhi bent a rope to form a circle.If she got the circumference of the circle is 30cm more than its diameter. What was the length of the radius?
easy peasy here we go..
so first circumference = 2π R
now it is given that circumference - 30 cm = Diameter;
Diameter = 2πR - 30 = 2 R { diameter = 2 times Radius}
now solving equations:
2πR -2R = 30
πR - R = 15
R ( π - 1 ) = 15
R ( 22/7 - 1) = 15
R ( 15/7 ) = 15
R = 15 x 7 / 15
R = 7 cm
Mark as brainliest
Answer:
7.01 cm
Step-by-step explanation:
Circumference = 2πr
=> d + 30 = 2πr
=> 2r + 30 = 2πr
=> 2r(π - 1) = 30
=> 2.14r = 15
=> r = 15/2.14
=> r = 7.01 cm
Peter works 52hours in a 40-hour work week where his basic wages rate is $200.If overtime is paid at time and-a-half, determine his wage for the week.
Answer:
$230
Step-by-step explanation:
Hes paid 200 for his wages but if he works overtime by 12 hours he gets half of the 5 dollars he earns per hour which is 2.5 which then is 2.5 times 12 which is then 30 plus the 200 he earned for the 40 hours.
Reflect quadrilateral ABCD across the line y = -2. Write the coordinates of the new vertices.
If the coordimate is reflected over y = -2, hence the resulting coordinate wil be A = (4, -2), B = (2, 3), C = (-6, 2) and D = (2, 2)
Reflection off coordinatesGiven the coordinate of the quadrilateral shown below
A = (-2, -2)
B = (-1, 3)
C = (3, 2
D = (-1, 2)
Reflecting the coordinates over the y - axis will give:
A = (2, -2)
B = (1, 3)
C = (-3, 2)
D = (1, 2)
If the coordimate is reflected over y = -2, hence the resulting coordinate wil be:
A = (4, -2)
B = (2, 3)
C = (-6, 2)
D = (2, 2)

Grayson needs to order some new supplies for the restaurant where he works. The
restaurant needs at least 761 forks. There are currently 205 forks. If each set on sale
contains 10 forks, which inequality can be used to determine x, the minimum
number of sets of forks Grayson should buy?
The inequality that can be used to determine x, the minimum number of sets of forks Grayson should buy is as follows:
761 ≥ 10x + 205
InequalityInequality equations are represented with <, >, ≤, or ≥.
Therefore,
The restaurant needs at least 761 forks . Therefore, the number of forks should be greater than or equals to 761.
He already has 205 forks.
Each sets on sale contains 10 fork.
x = minimum number of sets of forks he should buy.
Therefore, the inequality to represent the situation is as follows:

Step-by-step explanation:
a) To find the length of diagonal XT, we can use the distance formula to get [tex]\sqrt{(-3-5)^{2}+(4-(-2))^{2}}=10[/tex]
Since this is a rectangle, XT=YW, meaning YW=10 as well.
b) The area of a rectangle is given by length times width. The length is |-3-5|=8, and the width is |-2-4|=6. So the area is (8)(6)=48.
c) The perimeter is just 2(8+6)=28.

How to find the factor of polynomial?The factor of a polynomial is the terms in linear or equation form, which are when multiplied together, give the original polynomial equation as result.
Find these factors by taking out the common factors.
The given polynomial equation in the problem is,
[tex]x^3+ 7x^2 -2x - 14[/tex]
The above equation has the unknown variable x and the highest power of this unknown variable is 3.
Take out the highest common factor x², which can divide each term of the first two terms of equation (x³, 7x²). Thus,
[tex]x^2(x+ 7) -2x - 14[/tex]
Take out the highest common factor -2 from the second two terms as,
[tex]x^2(x+ 7) -2(x + 7)[/tex]
Now take out the common group (x+7) as,

Answer:
x = 6, ∠B = 50°
Step-by-step explanation:
a) 8x + 2 + 70 + 60 = 180
8x + 132 = 180
8x = 180 - 132 = 48
x = 48/8 = 6
b) ∠B = 180 - 70 - 60 = 50°
or 8x + 2 = 8*6 + 2 = 50°
Use the arc length formula to find the length of the curve y = 2 − x2 , 0 ≤ x ≤ 1. Check your answer by noting that the curve is part of a circle.
By using the arc length formula, we will see that the length of the curve is L = 1.48
How to use the arc length formula?
Here we have the curve:
y = 2 - x^2 with 0 ≤ x ≤ 1
And we want to find the length of the curve.
The arc length formula for a curve y in the interval [x₁, x₂] is given by:
[tex]L =\int\limits^{x_2}_{x_1} {\sqrt{1 + \frac{dy}{dx}^2} } } \, dx[/tex]
For our curve, we have:
dy/dx = -2x
And the interval is [0, 1]
Replacing that we get:
[tex]L =\int\limits^{1}_{0} {\sqrt{1 + (-2x)^2} } } \, dx\\\\L \int\limits^{1}_{0} {\sqrt{1 + 4x^2} } } \, dx\\[/tex]
This integral is not trivial, using a table you can see that this is equal to:
[tex]L = (\frac{Arsinh(2x)}{4} + \frac{x*\sqrt{4x^2 + 1} }{2})[/tex]
evaluated from x = 1 to x = 0, when we do that, we will get:
[tex]L = \frac{Arsinh(2) + 2*\sqrt{5} }{4} = 1.48[/tex]
That is the length of the curve.
