Exterior Angle=72 degrees.
Find the interior angle measure
and the number of sides of the polygon.
Answer:
The interior angle would measure [tex]108^{\circ}[/tex]. Assuming that this polygon is regular, it would contain [tex]5[/tex] sides.
Step-by-step explanation:
An exterior angle in a polygon is supplementary with the interior angle that shares the same vertex with the exterior angle. In other words, the sum of these two angles would be [tex]180^{\circ}[/tex].
In this question, the exterior angle measures [tex]72^{\circ}[/tex]. Therefore, the interior angle that shares the same vertex with this [tex]72^{\circ}\![/tex] exterior angle would measure [tex](180^{\circ} - 72^{\circ})[/tex], which is [tex]108^{\circ}[/tex].
The sum of all interior angles in a polygon with [tex]n[/tex] sides (regular or not) is [tex]180\, (n - 2)[/tex] degrees.
All the interior angles in a regular polygon are equal. Hence, in a regular polygon with [tex]n[/tex] sides (and hence [tex]n\![/tex] vertices,) each of the [tex]n\!\![/tex] interior angles would measure [tex]180\, (n - 2) / n[/tex] degrees.
Assume that the polygon in this question is regular. Again, let [tex]n[/tex] be the number of sides in this polygon. Each interior angle would measure [tex]180\, (n - 2) / n[/tex] degrees. However, it was also deduced that an interior angle of this polygon measures [tex]108^{\circ}[/tex]. That is:
[tex]\displaystyle \frac{180 \, (n - 2)}{n} = 108[/tex].
Solve for [tex]n[/tex]:
[tex]180\, n - 2 \times 180 = 108\, n[/tex].
[tex](180 - 108)\, n = 360[/tex].
[tex]\begin{aligned}n &= \frac{360}{180 -108} \\ &= \frac{360}{72} \\ &= 5\end{aligned}[/tex].
In other words, if this polygon is regular, it would contain [tex]5[/tex] sides.
2.932789 rounded to the nearest 10th
Answer:
2.9
Step-by-step explanation:
9 is in the tens place, and 3 is in the hundreds place. If the number in the hundreds place is less than the number in the tens place, the tens place stays the same. You just shorten the number.
So 2.932789 becomes 2.9
Determine which figures are congruent to Figure A. Follow the steps given as you investigate each shape. • Make a conjecture about which figures are congruent to Figure A. • Use patty paper to investigate your conjecture. Justify your conjecture by stating how you can move from Figure A to each congruent figure by sliding. flipping, or spinning Figure A.
Answer: I think Figure D and A are congruent
Step-by-step explanation: Remember: congruent means the same (in geometry) so if im wrong. Then you could figure out for yourself which ones look the same. Good luck

Chose the step below that correctly uses the division property to begin solving the equation: 2x − 8 = 4
A. x - 8 = 4
B. x - 4 = 2
C. x - 8 = 2
D. 2x = 12
Answer:
D
Step-by-step explanation:
2x. add 8 to other side. you get 2x=12
The correct answer would be an option (D) 2x = 12 which correctly uses the division property to begin solving the equation: 2x − 8 = 4
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that performs the arithmetic operations are called arithmetic operators.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
We have given the equation as
⇒ 2x − 8 = 4
⇒ 2x = 4 + 8
⇒ 2x = 12
⇒ x = 12/2
Apply the division operation on both sides
⇒ x = 6
Hence, the correct answer would be an option (D) 2x = 12 that correctly uses the division property to begin solving the equation: 2x − 8 = 4

Use the diagram 3 and 4 complementary 1.True 2.False
Answer:
False
Step-by-step explanation:
Complementary means the angles add up to a sum of 90⁰ and 3 and 4 add up to 180⁰ (considering the angles added together make a flat line and a flat line is 180⁰)
a sum of two angles that's add up to 180⁰ is what we call supplementary.

Solve for the value of v.
Answer:
9
Step-by-step explanation:
Since it is a straight line, therefore it will always be 180°
So...
(8v +3) +105 = 180
8v + 3 + 105 = 180
8v = 180 - 108
V = 72/8
= 9
Answer:
[tex]\boxed {\boxed {\sf v=9}}[/tex]
Step-by-step explanation:
In the diagram, there are 2 angles: 105° and (8v+3)°. They are on a straight line together, so they are supplementary angles. They must add to 180 degrees. We can set up an equation.
[tex]105 + (8v+3) = 180[/tex]
We are solving for v, so we must isolate the variable. First, we can rearrange the right side and combine the like terms (the constants without a variable).
[tex]105 +8v+3= 180 \\8v + (105+3) = 180 \\8v + 108= 180[/tex]
108 is being added to 8v. The inverse operation of addition is subtraction. Subtract 108 from both sides of the equation.
[tex]8v+108-108= 180-108 \\8v= 180-108 \\8v=72[/tex]
v is being multiplied by 8. The inverse operation of multiplication is division. Divide both sides by 8.
[tex]\frac {8v}{8}= \frac{72}{8}\\[/tex]
[tex]v= \frac{72}{8}[/tex]
[tex]v=9[/tex]
v is equal to 9.

120 feet, and the water shoot up 50 feet above the barrel of the water cannon.
Write a function that models the path of the water.
The answer is "parabola [tex]y =-0.0139(x-60)^2+50[/tex]", and the further calculation can be defined as follows:
Let's all describe the circumstance in an XY plane and then let the origin (0,0) indicate the parabola's initial point.The last point now, so because the diameter of the parabola is 120 feet (120, 0).It is stated that, as a result of the water shots at 50 feet just above the cannon barrel, the vertex of such a parabola shall be, as shown in the picture below, (60, 50) as a parabola is a symmetric figure.Now, we know (h,k) that the general parabolic equation[tex]y = a(x-h)^2+k[/tex][tex](h,k)=(60, 50)[/tex] the equation will thus be [tex]y=a(x-60)^2+50[/tex]Since we assume, the graph, therefore, crosses from point [tex](0,0)[/tex][tex]y =a(x-60)^2+50\\\\0=a(0-60)^2 + 50\\\\0 = 3600a + 50 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{(subtract 50 from both sides)}\\\\0 - 50 = 3600a + 50 - 50\\\\-50=3600a \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{(divide both sides by 3600)}\\\\\frac{-50}{3600}=\frac{3600 a}{3600} \\\\-0.0139 \approx a \\\\a \approx -0.0139[/tex]
Therefore, the equation of the given parabola is [tex]y =-0.0139(x-60)^2+50[/tex]
