x = [? ]°
117
124°
107
102
145
Answer:
x = 125°
Step-by-step explanation:
The sum of angles in an n-sided polygon is (180°)(n -2). For a hexagon, the sum of angles is ...
(180°)(6 -2) = 720°
We can use this to find x.
x +117° +124° +102° +145° +107° = 720°
x = 720° -595°
x = 125°

Answer:
A= 695.3cm²
Step-by-step explanation:
We khow that the area of anctagon is : A= 2(1+[tex]\sqrt{2}[/tex])*a² with a the side so A= 2(1+√2)*a² = 695.29= 695.3 cm²What's the correct algebraic translation of the following sentence?

Find the complementary angle for 93
Answer:
Complementary means they add up to 90, so you want 2 angles that add up to 90...so what do you mean for 93? Are you talking supplementary,(add to 180), because that would be 87.
Answer: no complement
Explanation: To find the complement of a 93 degree angle, we take 90 minus the measure of the angle which in this case is 90° - 93°.
Notice that this gives us a negative angle measure
and since we can't have a negative angle,
we say that the given angle has no complement.
Watch out for negative answers to geometry problems.
Since we're usually talking about angle measures
or segment lengths, negatives will not work.
A bowl contains equal numbers of red, orange, green, blue, and yellow candies. Kaz eats all of the green candies and half of the orange ones. Next, he eats half of the remaining pieces of each color. Finally, he eats red and yellow candies in equal proportions until the total number of remaining candies of all colors equals 15% of the original number. What percent of the red candies remain
Answer: 0%
Step-by-step explanation:
There are 5 colors of jelly beans.
Kaz ate all the green beans, so now only 80% of the jelly beans remain.
Kaz ate half of the orange pieces so now only 70% of the jelly beans remain.
Then Kaz ate half of the remaining pieces, so only 35% of the beans remain.
Current numbers: 0% green, 5% orange, 10% red, yellow, blue
Then he eats red and yellow candies in equal proportions until only 15% of the beans remain. This means that he ate 20% worth of red and yellow beans. This means that he ate all of the red and yellow beans.
Thus, there are 0% red beans left.
Below is the work a student completed with an error. Identify the step where the error occurred and give the correct solution. Step 1:(12-20)-3(8-3)+13 Step 2:-8-24-9+13 Step 3:-32-9+13 Step 4:-41+13
Answer:
The error is in Step 2. The student distributed -3 incorrectly; it should have been 9, not -9. The correct solution is -8 - 24 + 9 + 13 = -32 + 9 + 13 = -32 + 22 = -10.

Hi! :)
Answer:
-1.6 or -1 3/5
Step-by-step explanation:
This is how I got -1 3/5
First we have to convert the mixed number into fractions.
Than you have to use the formula
(Top) -7 x 8
(Bottom) 5x7
And you will get -56/35
Now you have to convert-56/25 into mixed number
Which will be -1 3/5
So the answer is -1 3/5 or -1.6

Triangle $ABC$ has its vertices $A$, $B$, and $C$ on the sides of a rectangle 4 units by 5 units as shown. What is the area of triangle $ABC$ in square units?
Answer:
10 square units.
Step-by-step explanation:
It is given that triangle ABC has its vertices A, B, and C on the sides of a rectangle 4 units by 5 units.
Height of triangle = 4 units
Base of triangle = 5 units
We need to find the area of triangle.
Area of triangle [tex]=\dfrac{1}{2}\times base \times height[/tex]
Substitute base = 5 and height = 4 in the above formula.
Area of triangle [tex]=\dfrac{1}{2}\times 5\times 4[/tex]
Area of triangle [tex]=\dfrac{20}{2}[/tex]
Area of triangle [tex]=10[/tex]
Therefore, the area of triangle ABC is 10 square units.

Trapezoid ABCD is rotated 180 degrees about the origin and then reflected over the x-axis, followed by a reflection over the y-axis. What is the location of point A after the transformations are complete?
Answer:
the location of point A after the transformations are complete is (-5, 1)
Step-by-step explanation:
Given the coordinate of the trapezoid at A(-5, 1), B(-4, 3), C(-1, 3) and D(-2, 1).
The location of point A is at (-5, 1) which is the second quadrant, when it is rotated 180 degrees about the origin, the point moves to the fourth quadrant and the new point is at (5, -1). If it is then reflected over the x axis, the x coordinate remain the same and the sign of the y coordinate changes making the new point (5, 1). If it is then reflected over the y axis, the y coordinate remain the same and the sign of the x coordinate changes making the new point (-5, 1).
the location of point A after the transformations are complete is (-5, 1)
Answer:
the location of point A after the transformations are complete is (-5, 1)

what is this answer 4\5+2\10
Answer:

Step-by-step explanation:
To add fractions, we need to make the denominators the same. Luckily, we can simplify 2/10 to 1/5. Now that the denominators are both 5, we can add. When adding fractions, we only add the numerator, and the denominator remains the same, so we'd do 4+1/5, which equals 5/5, which simplifies to 1.

If Q and T are midpoints, then the triangles URS and UQT are similar triangles and verify the following proportions:
[tex]\frac{QT}{RS} =\frac{UQ}{UR} =\frac{UT}{US} =\frac{1}{2}[/tex]
and all should equal 1/2 because Q and T are midpoints.
Then we study in particular the proportion:
[tex]\frac{QT}{RS} =\frac{1}{2}[/tex]
since we know both segments can be expressed in terms of "p" as indicated in the problem:
[tex]\frac{QT}{RS} =\frac{1}{2}\\\frac{p-87}{p-74} =\frac{1}{2}\\2(p-87)=p-74\\2p-174=p-74\\2p-p=174-74\\p=100[/tex]
The triangles below are similar. What is the length of ? A. 17 cm C. 19 cm B. 18 cm D. 20 cm
Answer:
B. 18 cm.
Step-by-step explanation:
Because they are similar, we can say that segment AC corresponds to segment DF, and segment AB corresponds to segment ED. So, we can set up a proportion.
[tex]\frac{16}{24} =\frac{12}{x}[/tex]
[tex]\frac{2}{3} =\frac{12}{x}[/tex]
2 * x = 12 * 3
2x = 36
x = 18
So, the length of ED is B. 18 cm.

V = 4/3 πr³ cubic units
A sphere fits perfectly into the cylinder as shown, touching the top and bottom of the cylinder.
If the height of the cylinder is 32 inches.
The height of the cylinder and sphere are same.
Then the radius of the sphere will be
r = 32 / 2
r = 16 inches
Then the volume of the sphere will be
V = 4/3 π(16)³ cubic units
V = 5461.3 π cubic inches
Then the correct option is D.

Required probability:

Hope this helps...
Good luck on your assignment..
Answer:
1/8
Step-by-step explanation:
The probability of getting a yellow can be found by dividing the number of yellow sections by the total number of sections.
P(yellow)= yellow/total
There is only 1 yellow section out of a total of 8 sections.
yellow= 1
total= 8
P(yellow)= 1/8
This fraction cannot be reduced further, so our answer is 1/8.
An interior angle of a regular convex polygon is 135°. How many sides does the polygon have?
Hey there! :)
Answer:
The polygon has 8 sides.
Step-by-step explanation:
Use the sum of interior angles formula to solve.
The sum of the interior angles is equal to (n-2)180. If 135° is one angle, we can simply set up an expression to represent this situation:
135 = (n-2)· 180 / n
Multiply both sides by n:
135n = (n-2) · 180
Distribute the 180:
135n = 180n - 360
Subtract 180n from both sides:
-45n = -360
Divide both sides by -45:
n = 8. The polygon has 8 sides.
Answer:8 sides
