Answer:
polygon B = 20 meters
Step-by-step explanation:
polygon A : polygon B
3 : 4
15 : x
first take 15 and divide by 3, this would tell us how much it went up by:
15 ÷ 3 = 5
next, take 4 and multiply it by 5:
4 x 5 = 20
this means that polygon B is 20 meters

Determine the value of each unknown angles.
HELP PLEASE DO ANY! I’ll give you brilliance
For D:
A triangle always has 180 degrees total. No more, no less. Seeing as though all the sides and angles are the same length, we can just divide 180 by 3, giving us 60. x = 60 degrees.
For E:
We can see there is a 90 degree symbol that surmises both angles. We know the lower angle is 30 degrees, so m must equal 60 degrees.
For G:
Same concept as D, except we gotta do a bit of math. A triangle always has 180 degrees, So we add 50 and 55 together and get 105. Subtract 105 from 180 and we get 75. Therefore, your angle is 75 degrees.
For H:
The 75 degree angle and m are parallel, with the same line passing through it, meaning that m is identical to the other angle. m = 75.
Answer:
d) x = 60
e) m = 60
g) q = 75
h) m = 75
Step-by-step explanation:
d) This image is that of an equilateral triangle, or a triangle whose sides are all equal (also known as a regular triangle). One property of an equilateral triangle is that all of its angles are also equal. Because the angles of a triangle add up to 180° (Triangle Sum Theorem), each angle would be 180/3°, or 60°, so x = 60.
e) This problem shows two complementary angles. Complementary angles are two angles that add up to 90°. Because one of the angles is given, you can find the other by subtracting the given one from 90°:
m = 90 - 30
m = 60
g) This is an image of a triangle with two given angles and the missing one is the third angle, q. You can solve for q using the Triangle Sum Theorem, which states that the three interior angles of a triangle add to 180°:
50 + 55 + q = 180
105 + q = 180
q = 75
h) This image shows two parallel lines cut by a transversal. You can find m using the Corresponding Angles Theorem, which states that if parallel lines are cut by a transversal, the corresponding angles will be congruent. Because the lines are parallel, you know that m = 75 since the 75° angle is its corresponding angle.
The diagram shows a solid metal cuboid.
The areas of three of the faces are marked on
the diagram.
The lengths, in cm, of the edges of the cuboid
are whole numbers.
The metal cuboid is melted and made into cubes.
Each of the cubes has sides of length 2.5 cm.
Work out the greatest number of these cubes that can be made.
You must show your working.
Answer:
6 cubes
Step-by-step explanation:
Considering the given cuboid, it can be deduced that;
length of the cuboid = 7 cm
width of the cuboid = 3 cm
height of the cuboid = 5 cm
Thus,
volume of the cuboid = length x width x height
= 7 x 3 x 5
= 105 cubic centimetres
The cubes has sides of length 2.5 cm.
volume of each cube = length x width x height
= 2.5 x 2.5 x 2.5
= 15.625 cubic centimetres
The greatest number of cubes that can be made = [tex]\frac{105}{15.625}[/tex]
= 6.72
The greatest number of cubes that can be made from the cuboid is 6.

Can you please help solve for x?
x+6+x-2=180
Answer:
x=88
Explanation:
x+6+x-2=180
2x+4=180
2x=180-4
2x=176
*divivd both sides*
x=88
Answer:
x = 88
A = 94°
B = 102°
C = 86°
D = 78°
Step-by-step explanation:
We find the angle measurements by finding x first.
what we first do in this equation x+6+x-2=180 is combine like terms
this would equal
2x+4=180
we want x by itself so we subtract 4 from both sides
this would equal
2x=176
x is still not by itself so now we divide 2 by both sides
this would equal
x = 88
Now we just plug in our answers in to the angles meaning
we replace everything that is x in the quadrilateral with 88
Now that we found all the sides with equations there is still one angle that is undefined
We figure this out by subtracting all the angles with 360.
this is because all the angles degrees added in a quadrilateral equals 360. so 360-258=102
so the angle measurement of angle B is 102
Which set of ordered pairs demonstrates a function?
A
(-2,-4), (-1, -2), (1, 2), (2, 4)
B
(-2, 4), (1, 2), (1, -2), (2.-4)
C
(-2,4), (-1, 2). (-1, 2), (-2,-4)
D
(-2, 4). (-1, 2), (-1, -2), (-2,-4)
The set of ordered pairs from listed options demonstrating a function is given by: Option A: (-2,-4), (-1, -2), (1, 2), (2, 4)
Firstly, we need the definition a function; based on which we can distinguish the correct set of ordered pairs.
What is a function?If we have two sets A and B as:
[tex]A = \{a_1, a_2, ... \}\\B = \{b_1, b_2, ... \}[/tex]
Then, function [tex]f: A \rightarrow B[/tex] is a connection of elements of A to B such that one element of A is connected to only single element of B, and not many.
The connected pairs are then written as:
[tex]\{(a_i_1,b_j_1), (a_i_2, b_j_2), ... \}[/tex] under the function f.
Now, for the listed ordered pairs, checking if they're functions or not:
Case 1: (-2,-4), (-1, -2), (1, 2), (2, 4)Each single input is connected with single output. So it is demonstrating a function.
Case 2: (-2, 4), (1, 2), (1, -2), (2.-4)In this case, 1 is connected to 2, and -2 both. Thus, it's not representing a function.
Case 3: (-2,4), (-1, 2), (-1, 2), (-2,-4)-1 is only connected to 2, but that does't help as -2 is connected to -4 and 4 both. Thus, it doesn't represent a function.
Case 4: (-2, 4), (-1, 2), (-1, -2), (-2,-4)-2 is connected to 4 and -4, and -1 is connected to 4 and -4, so its not a function.
Thus, the set of ordered pairs from listed options demonstrating a function is given by: Option A: (-2,-4), (-1, -2), (1, 2), (2, 4)

The cross-sections of the solids are sectors. Find the surface area, rounding your answer to 1 decimal place.
Answer:
The total surface area of the figure is approximately 10.2 m²
Step-by-step explanation:
The dimensions of the solid are;
The shape of the solid = An half cylinder
The diameter of the cylinder, D = 1.6 m
The length of the cylinder, l = 2 m
The surface area of the curved part of the solid = π × D × l ÷ 2
Therefore;
The surface area of the curved part of the solid = π × (1.6 m) × 2 m/2 ≈ 5.03 m²
The area of the curved surface, V = 5.03 m²
The area of the rectangular top, A = 1.6 m × 2 m = 3.2 m²
The area surface of the semi-circular sides of the figure = 2 × π·D²/4 ÷ 2
Therefore;
The area surface of the semi-circular sides of the figure = 2 ×π × (1.6 m)²/4 ÷ 2 ≈ 2.01 m²
The total surface area of the figure, A = 5.03 m² + 3.2 m² + 2.01 m² = 10.24 m²
The total surface area of the figure ≈ 10.2 m² (rounding to 1 decimal place)
