Answer:
The polygon with an interior angle sum of 1080° is an octagon or a polygon with 8 sides. We are given that the interior angle sum of our polygon
Step-by-step explanation:
Sorry if it's wrong.
Answer:
Step-by-step explanation:
Remark
First of all, you need a regular polygon, otherwise the question can have all sorts of interior angles. The standard way to solve this is set up an equation that looks like this.
(n - 2)*180 = 1080 Divide by 180
(n - 2) = 1080/180
n - 2 = 6 Add 2 to both sides.
n = 6 + 2
n = 8
Conclusion
So an 8 sided figure has 8 interior angles that add up to 1080 if the 8 sided figure is regular.

Which pair of functions are inverses of each other?
Help help help!!!!!
Answer:
b
Step-by-step explanation:
check 1 by 1
a. [tex]y=\frac{\sqrt[3]{x}}{5}[/tex]
[tex]x=\frac{\sqrt[3]{y} }{5}[/tex]
125x^3=y which is not equal to g(x)
b. y=2x-9
inverse= x=2y-9
x+9=2y
y=(x+9)/2 which is equal to g(x). B is the answer.
Find the value of x. Round to the nearest tenth.

Step-by-step explanation:
A bridge can hold at most 80,000 pounds. A tow truck weighing 7,000 pounds is broken down on the bridge. If the average car weights 2,800 pounds, how many cars can safety be on the bridge with the broken down tow truck.
Answer:
26
Step-by-step explanation:
x = number of cars that an safety be on the bridge with the broken down tow truck.
The equation that can be used to determine the answer =
total weight the bridge can accommodate = total weight of truck + total weight of cars
total weight of cars = weight of a car x total number of cars
2800x
80,000 = 7000 + 2800x
collect like terms
80,000 - 7000 = 2800x
73,000 = 2800x
x = 73,000 / 2800
x = 26

Find x and y
Show all the work
Answer:
x=27°
y=4 units
Step-by-step explanation:
To find x:
The sum of all the angles in a quadrilateral is 360°. In a rhombus (you know it's a rhombus because it's a quatrilateral where all the sides are congruent), opposite angles are congruent. Because you're given that the measure of ∠T is 127°, you also know that m∠V=127°. You also know that m∠U=m∠S=(2x-1)°.
Using this information, set up an equation.
127+127+(2x-1)+(2x-1)=360
You can just divide both sides by 2 to get:
127+(2x-1)=180
Then, just solve for x.
127+2x-1=180
2x+126=180
2x=54
x=27°
To find y:
All the sides are given to be congruent. That's what the little marks on the sides mean, and that's how we knew it was a rhombus earlier.
So SV=VU=UT=TS
SV=6y-5
VU=3y+7
Since SV=VU:
6y-5=3y+7
Solve for y.
3y=12
y=4

KL, LM, MN and KN are tangent to the circle. what is the perimeter of KLMN
Answer:
perimeter = 46
Step-by-step explanation:
Segments of tangents to a circle from the same external point are congruent.
KL = 3 + 4 = 7
LM = 4 + 10 = 14
MN = 10 + 6 = 16
NK = 6 + 3 = 9
Perimeter = 7 + 14 + 16 + 9 = 46

Answer:
CA = 32
Step-by-step explanation:
By intersecting chords theorem:
[tex]12(4x + 1) = 14(3 + 3x) \\ \\ 48x + 12 = 42 + 42x \\ \\ 48x - 42x = 42 - 12 \\ \\ 6x = 30 \\ \\ x = \frac{30}{6} \\ \\ x = 5[/tex]
CA = 14 + ( 3 + 3x)
CA = 14 + ( 3 + 3*5)
CA = 14 + ( 3 + 15)
CA = 14 + 18
CA = 32

Answer:
area: 1070
perimeter: 434 units
Step-by-step explanation:
area:
- use pythagoream theorem to find the height, which is gonna be 84
- from there, you're gonna wanna find the area of the rectangle and then the two triangles. the way i do it is by just finding the area of the rectangle first, 100x84 = 8400, and then finding the area of the triangles (35x84/2 = 1470 and 20x84/2 = 840)
- you have the area of all shapes, now just add them together (8400+1470+840 = 10710)
perimeter:
just add all the lengths given together.

how many different right triangles are there with a hypotenuse of lenght 5 cm
Answer:
Draw a horizontal line across a page of paper, somewhere in the middle. Mark a point A on the line, toward the left margin.
Spread open a compass to make good sized circle, but so that if the point of the compass is on the point you drew, the pencil fits on the page, both below the top edge and to the left of the right edge of the page. Draw the arc, from roughly the 12 O’Clock position over and down to the intersection of the line segment, at the 3 O’Clock position.
Call the opening of your compass, the radius of the arc you just drew, “5 units”.
Pick any point on the arc between the 12 and 3 positions, B. Drop a line down from that point B, perpendicular to the original horizontal line. Label the point that it intersects the horizontal line, C.
ABC is a right triangle with hypotenuse 5. Do this again with a point a little closer to the 3 O’Clock position. It’s another right triangle with hypotenuse 5.
Indeed, as you get closer to the right, along the arc, the height of the triangle declines, but the width of the triangle increases. The hypotenuse remains 5 in all cases. We picked points on the circle. We could have picked points on the horizontal line first, and raised perpendicular lines until they intersected the circle. Each point forms a distinct right triangle.
There are as many possible right triangles as there are possible points in a line segment.

fig., QR is a common tangent to the given circles,
touching externally at the point T. The tangent at T
meets QR at P. If PT = 3.8 cm,then find the length of QR.
Answer:
QR = 7.6 cm
Step-by-step explanation:
By theorem of tangents drawn from an external point to a circle,
"Tangents drawn from an external point to a circle are equal in measure"
By this property,
PQ = PT = 3.8 cm
And PR = PT = 3.8 cm
Since, QR = PQ + PR [By segment addition postulate]
QR = 3.8 + 3.8
QR = 7.6 cm

Find X and TU
Show all the work
Answer:
x = 10, TU = 24
Step-by-step explanation:
The midsegment TU is half the sum of the parallel bases, that is
[tex]\frac{1}{2}[/tex] (3x + 2+ 2x - 4 ) = 2x + 4 ( multiply both sides by 2 to clear the fraction )
5x - 2 = 4x + 8 ( subtract 4x from both sides )
x - 2 = 8 ( add 2 to both sides )
x = 10
Then
TU = 2x + 4 = 2(10) + 4 = 20 + 4 = 24
10090 7 Each railroad car in a train set is 6 inches in length. The railroad track is 5 feet long. How many railroad cars can it on the track ?
Answer: 10 railroad cars
Step-by-step explanation:
1 feet = 12 inches
Each railroad car is 6 inches in length which is half of 1 feet. If we add another railroad car, then both of them altogether will be 1 feet long.
So, if 1 feet = 2 railroad cars
then, 5 feet = 2 x 5
= 10 railroad cars
