Answer:
The equation to find the length of one side of a pentagon using the radius looks like this: {display style side length=2rsin ({frac {180} {n}})}. It may look a little complicated, but you can easily plug in the numbers that you already know to simplify the equation and find the length of a side. r represents the radius of the pentagon.

How do I do this problem (similar right triangles) please explain how you did it!!
ASAP!!!
Answer:
by phythagoras theorem
(c+b)^2=(8)^2+(6)^2
(b+c)^2=64+36
(b+c)^2=100
b+c=√100
b+c=10.
by phythagoras theorem
(8)^2=(a)^2+(b)^2
64-b^2=a^2. {1}
by phythagoras theorem
(6)^2=(a)^2+(c)^2
36-c^2=a^2. {2}
In equation 1 and 2,
64-b^2=36-c^2
64-36= -c^2+b^2
28= b^2-c^2
28=(b+c)(b-c)
28=10(b-c)
b-c=28/10
b-c=2.8.
b+c=10
b-c=2.8
subtract both equations
c=3.6
option A is correct.
What is the slope of the line?
Thanks if you help
Answer:
The slope of the line is 2.
Step-by-step explanation:
you can simply do this by using the method rise/run. You count how much it takes to get from one point to the other. Go Upwards twice and to the right once which gives you 2/1 which is 2.

Katelyn was designing a cover for her binder and needed to cut some construction paper. The construction paper length can be represented by the expression (a2 + 7a - 3) if katelyn cut a piece that was (2a+5) long, how much construction paper is left
Answer:
a² + 5a - 8
Step-by-step explanation:
If the construction paper has a length of a² + 7a - 3, and Katelyn cut a piece 2a + 5 long, the amount of construction paper that would be left is,
a² + 7a - 3 - (2a + 5)
= a² + 7a - 3 - 2a - 5
collecting like terms, we have
= a² + 7a - 2a - 3 - 5
simplifying, we have
= a² + 5a - 8

Trigonometric Ratios
The ratios between the sides of a right triangle are called trigonometric ratios.
If any of the acute angles is chosen as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides and the hypotenuse.
The image shows a right triangle with a tree and the ground forming a right angle and an elevation angle of 33°.
This angle of 33° has a side of 30.5 m as its adjacent leg and the height of the tree X as the opposite side.
The trigonometric ratio that relates both legs is the tangent:
[tex]\displaystyle \tan 33^\circ=\frac{X}{30.5}[/tex]
Solving for X
[tex]X=30.5\cdot \tan 33^\circ[/tex]
Using a calculator:
X = 19.81 m
The height of the tree is 19.81 m

two parallel lines are cut by a transversal as shown below. Suppose m<8=131. Find m<1 and m<3.
Answer:
m∠1 is 49° and m∠3 is 49°
Step-by-step explanation:
In the given figure
∵ There are 2 parallel lines
∵ A transversal cuts them
∴ ∠4 and ∠8 are corresponding angles
→ Corresponding angles are equal in measures
∴ m∠4 = m∠8
∵ m∠8 = 131°
∴ m∠4 = 131°
∵ ∠1 and ∠4 formed a pair of linear angle
∵ The sum of the measures of the linear angles is 180°
∴ m∠1 + m∠4 = 180°
→ Substitute ∠4 by 131°
∴ m∠1 + 131° = 180°
→ Subtract 131 from both sides
∵ m∠1 + 131 - 131 = 180 - 131
∴ m∠1 = 49°
∵ ∠1 and ∠3 are vertically opposite angles
∴ m∠1 = m∠3
∵ m∠1 = 49°
∴ m∠3 = 49°

Jeremy spent the entire weekend earning money by working around his neighborhood 15% of his total earnings was from raking leaves and $36 mowing lawns and earn the rest of his money walking dogs the end of the weekend with earning $90 how much money did he earn by walking dogs?
Answer: $40.50
Step-by-step explanation:
Since 15% of his total earnings was from raking leaves. The earning from taking leave will be:
= 15% × $90
= 0.15 × $90
= $13.50
Earnings from mowing lawns = $36
The earnings from walking dogs will be:
= $90 - $36 - $13.50
= $40.50
3x - 2y = -1 ; -x + 2y = -5
Answer: 1
−x+2y=−5;3x−2y=−1
Step: Solve−x+2y=−5for x:
−x+2y=−5
−x+2y+−2y=−5+−2y(Add -2y to both sides)
−x=−2y−5
−x
−1
=
−2y−5
−1
(Divide both sides by -1)
x=2y+5
Step: Substitute2y+5forxin3x−2y=−1:
3x−2y=−1
3(2y+5)−2y=−1
4y+15=−1(Simplify both sides of the equation)
4y+15+−15=−1+−15(Add -15 to both sides)
4y=−16
4y
4
=
−16
4
(Divide both sides by 4)
y=−4
Step: Substitute−4foryinx=2y+5:
x=2y+5
x=(2)(−4)+5
x=−3(Simplify both sides of the equation)
Answer:
x=−3 and y=−4

Please answer thank you
Answer:
0. If it's a horizontal line, then the slope if automatically 0. if the line went straight up the slope would be "no slope" or "unidentified" your problem has a horizontal line so the slope is 0
