PLEASE HELP ME ITS DUE In 10 mins please
Answers
Answer:
Step-by-step explanation:
Part A
Since, BDFHJ is a regular pentagon,
Measure of interior angles of this pentagon = [tex]\frac{(n-2)\times 180}{n}[/tex]
= [tex]\frac{(5-2)\times 180}{5}[/tex]
= 108°
Since, ∠ABC ≅ ∠JBD [Vertical angles]
Therefore, m∠ABC = m∠JBD = 108°
Part B
m∠JBD + mCBD = 180° [Linear pair of angles]
108° + m∠CBD = 180°
m∠CBD = 180 - 108
m∠CBD = 72°
Similarly, m∠BDF + m∠CDB = 180°
m∠CDB + 108° = 180°
m∠CDB = 180 - 108
= 72°
In ΔCBD,
m∠BCD + m∠CDB + m∠DBC = 180°
m∠BCD + 72° + 72° = 180°
m∠BCD = 180° - 144°
= 36°

Step-by-step explanation:
A1. C = 104°, b = 16, c = 25
Law of Sines: B = arcsin[b·sinC/c} ≅ 38.4°
A = 180-C-B = 37.6°
Law of Sines: a = c·sinA/sinC ≅ 15.7
A2. B = 56°, b = 17, c = 14
Law of Sines: C = arcsin[c·sinB/b] ≅43.1°
A = 180-B-C = 80.9°
Law of Sines: a = b·sinA/sinB ≅ 20.2
B1. B = 116°, a = 11, c = 15
Law of Cosines: b = √(a² + c² - 2ac·cosB) = 22.2
A = arccos{(b²+c²-a²)/(2bc) ≅26.5°
C = 180-A-B = 37.5°
B2. a=18, b=29, c=30
Law of Cosines: A = arccos{(b²+c²-a²)/(2bc) ≅ 35.5°
Law of Cosines: B = arccos[(a²+c²-b²)/(2ac) = 69.2°
C = 180-A-B = 75.3°

How many reflectional symmetries does this figure have?
Enter your answer in the box
reflectional symmetries
How many rotational symmetries does this figure have?
Enter your answer in the box
rotational symmetnes
Answers
Answer:
There are no reflectional symmetries.
Step-by-step explanation:
Hi there, a reflectional symmetry requires the reflection to mirror that of the figure being reflected. To put it in simpler terms, it should look exactly the same if you put one half right next to a mirror.
I hope this clears up things a bit.
The required, latter F does not have reflectional symmetries.
What is Reflection symmetry?Reflection symmetry is a type of symmetry where a figure is reflected across a line, called the line of symmetry, and the resulting figure is identical to the original. In other words, if you were to fold the figure along its line of symmetry, the two halves would match up perfectly.
Since we have given the figure of latter F, which does not have reflectional symmetries.
It's important to note that not all letters have reflectional symmetry, but the letter "F" is one example of a letter that does have this type of symmetry.

17. A rectangular prism has a length of 12 cm, a
height of 6/cm, and a width of 4 cm. Use the
formula SA = 2({w) + 2(wh) +2(ehy to find the
surface area of the rectangular prism.
Answers
Answer:
SA = 288 cm
Step-by-step explanation:
l = 12
w = 4
h = 6
SA = 2lw + 2wh + 2lh
SA = (2 x 12 x 4) + (2 x 4 x 6) + (2 x 12 x 6)
SA = 96 + 48 + 144
SA = 288

a. 8 cakes
c. 7 cakes
b. 2 cakes
d. 4 cakes
Answers
Answer:
a. 8
Step-by-step explanation: Out of 12 baked goods sold , let the number of cakes sold, be x in number and pies sold were 12 − x in number. Total sell was $ 144 , 1 cake costs $ 14 and 1 pie costs, $ 8 ∴ 14 ⋅ x + ( 12 − x ) ⋅ 8 = 144 or 14 x − 8 x = 144 − 96 or 6 x = 48 ∴ x = 8

kim has 8 vanilla candles, 4 cherry candles and 6 raspberry candles. what is the probability that kim will choose a cherry candle?
Answers
-8 vanilla
-4 cherry
-6 raspberry
4/18 would represent the number of cherry candles. this could also be written as 22.22%, or just 22%
hope i was able to help you!
The probability that Kim will choose a cherry candle is [tex]\frac{2}{9}[/tex] OR 0.22
From the question,
We are to determine the probability that Kim will choose a cherry candle out of the possible candles
From the given information
Number of vanilla candles = 8
Number of cherry candles = 4
Number pf raspberry candles = 6
∴ Total number of candles = 8 + 4 + 6 = 18
Using the formula
[tex]Probability = \frac{Number\ of\ favorable\ outcomes}{Total\ number\ of\ outcomes}[/tex]
For the probability to choose cherry candle
Number of favorable outcome = 4
Total number number of outcomes = 18
∴ Probability of choosing cherry candle = [tex]\frac{4}{18}[/tex]
Probability of choosing cherry candle = [tex]\frac{2}{9}[/tex] OR 0.22
Hence, the probability that Kim will choose a cherry candle is [tex]\frac{2}{9}[/tex] OR 0.22
