See the attachment below, co-interior angles lie at the same side of the transversal, or the line that crosses between the two parallel lines.
So if you are finding the co-interior angle of ∠AGH, then it is ∠CHG.
They are also supplementary angles and will add up to 180°.

30 IS 15% of WHAT number?
A. 333.3
B. 266.6
C. 600
D. 200
Answer:
The correct answer is D) 200
Step by step explanation:
Let x be the number:
Then,
→15/100(x)=30
→3/20(x)=30
→3x/20=30
→3x=20⋅30
→3x=600
→x=600/3=200
Hope it helps!
Answer:
D 200
Step-by-step explanation:
Let the number we are find be x. We can write this as an equation:
30 = 15%*x = (15/100)x
Multiplying by 100/15 on both sides to isolate x:
x = 30(100/15) = 2(100) = 200
Therefore, 200 is our answer. I hope this helps! :)

A bookmark shaped like a rectangle has a total perimeter of38cm the length of the one of its sides is 14 what is the width of each side of the bookmark in centimeters
Answer:
The Width of each side of the bookmark in centimeters = 5cm
Step-by-step explanation:
A bookmark shaped like a rectangle has a total perimeter of38cm the length of the one of its sides is 14 what is the width of each side of the bookmark in centimeters
The formula for perimeter fo a rectangle =
P = 2L + 2W
Where L = Length
W = Width
Hence: From the above question:
38cm = 2 × 14 cm + 2 W
38cm = 28cm + 2W
2W = 38cm - 28cm
2W = 10cm
W = 10cm/2
W = 5cm
Hence, the Width of the rectangle(each side of the bookmark in centimeters) = 5cm
Express 0.361 recurring as a fraction.
(only the 61 recurs)
9514 1404 393
Answer:
179/495
Step-by-step explanation:
When the repeating decimal starts at the decimal point, the repeating digits can be turned into a fraction by putting them over the same number of 9s. That is, 0.61616161... is equivalent to 61/99.
Here, the repeating part is 1/10 that value, so is 61/990. This is added to the non-repeating part, which is 0.3 = 3/10.
Then the entire decimal is ...
0.361_61 = 3/10 + 61/990 = (297 +61)/990 = 358/990 = 179/495

If A =30 and B =60. verifiy that 2 sin A cosA =2tanA/1+tan²A
Step-by-step explanation:
It's given that A = 30° . Lets find the sin , cos & tan of A
⇒ [tex]\sin A=\sin30 = \frac{1}{2}[/tex]
⇒ [tex]\cos A = \cos 30 = \frac{\sqrt{3} }{2}[/tex]
⇒[tex]\tan A = \tan 30 = \frac{1}{\sqrt{3} }[/tex]
Lets solve the LHS (Left Hand Side) :-
[tex]2(\sin A \times \cos A) = 2(\frac{1}{2} \times \frac{\sqrt{3} }{2}) = \frac{\sqrt{3} }{2}[/tex]
Now lets solve the RHS (Right Hand Side) :-
[tex]\frac{2\tan A}{1+\tan ^{2}A } = \frac{2 \times \frac{1}{\sqrt{3} } }{1 + (\frac{1}{\sqrt{3} } )^{2} } = \frac{2}{\sqrt{3} } \div ( 1 + \frac{1}{3} ) = \frac{2}{\sqrt{3} }\div \frac{4}{3} = \frac{2}{\sqrt{3} } \times\frac{3}{4} =\frac{\sqrt{3} }{2}[/tex]
∴ LHS = RHS ( Proved )

When you mix two colors of paint in equivalent ratios, the resulting color is always the same. How many cups of yellow paint should you mix with 3 cups of blue paint to make the same shade green? Explain.
Answer:
You should mix 15 cups of yellow paint, because it takes 5 cups of yellow paint + one cup of blue paint to make the same green. Since there's 3 cups of blue paint, multiply that by 5, and you get 15.

Proove that: tanα + cotα = secα. cosecα
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
tan a = [tex]\frac{sina}{cosa}[/tex], cot a = [tex]\frac{cosa}{sina}[/tex]
sec a = [tex]\frac{1}{cosa}[/tex], cosec a = [tex]\frac{1}{sina}[/tex]
Consider the left side
tana + cota
= [tex]\frac{sina}{cosa}[/tex] + [tex]\frac{cosa}{sina}[/tex]
= [tex]\frac{sin^2a+cos^2a}{cosasina}[/tex]
= [tex]\frac{1}{cosasina}[/tex]
= [tex]\frac{1}{cosa}[/tex] × [tex]\frac{1}{sina}[/tex]
= seca . coseca
= right side , thus proven
Create a binomial probability experiment with the data from the public opinion poll experiment. Use the probability of success and failure from the experiment. Calculate the probability of the number of successes in 100 random tests. For example, if the probability of success is 0.20 and the number of trials is 100, then the number of successes is 20.
give a real answer please this is important for my grade
Step-by-step explanation:
How do you calculate number of successes?
Example:
Define Success first. Success must be for a single trial. Success = "Rolling a 6 on a single die"
Define the probability of success (p): p = 1/6.
Find the probability of failure: q = 5/6.
Define the number of trials: n = 6.
Define the number of successes out of those trials: x = 2.
Binomial probability distribution for the given set of data is
[tex]\ 100C_{x[/tex][tex]( 0.20)^{x} (0.80)^{100-x}[/tex].
What is binomial probability distribution?"Binomial probability distribution is the representation of a probability with only two outcomes success and failure under given number of trials."
Formula used
Binomial probability distribution is given by
[tex]\\n{C}_{x}p^{x}q^{n-x}[/tex]
n= number of experiments
x = 0, 1, 2, 3,.......
p = probability of success
q = probability of failure
According to the question,
Number of trials 'n' = 100
Probability of success 'p' = (20 / 100)
= 0.20
Probability of failure 'q' = 1 - p
= 1 - (20/100)
= (80 / 100)
Substitute the value in the formula we get
Required probability = [tex]\ 100C_{x[/tex][tex]( 0.20)^{x} (0.80)^{100-x}[/tex]
Example:
Tossing a coin 6 times getting exactly two heads.
Number of trials 'n' = 6
Number of heads 'x' =2
Only two possible outcomes head or tail
Probability of getting head 'p' = 1 / 2
Probability of not getting head 'q' = 1 /2
Required probability = [tex]\ 6C_{2[/tex] (1/2)²(1/2) ⁶⁻²
=[tex]\ 6C_{2[/tex] (1/2)⁶
Hence, binomial probability distribution for the given set of data is
[tex]\ 100C_{x[/tex][tex]( 0.20)^{x} (0.80)^{100-x}[/tex]

30. Find the equation of straight line whose slope
is 3 times and y-intercept is double of the line
2x - 3y = 4.
Step-by-step explanation:
gradient/slope = 3
y-intercept
2x - 3y = 4
3y = 2x - 4
y = 2/3x - 4/3
so y-intercept is double -4/3 so... -4/3x2 = -8/3
the equation of the line is
y = 3x - 8/3 or 9x - 3y = 8
Answer:
3y=2x-8
Step-by-step explanation:
when y intercept x=0
2(0)-3y=4
-3y=4
y=-4/3
when x intercept y=0
2x -3(0)=4
2x =4
x=2
point (2,-4/3)
gradient
-3y=-2x +4
y=2x/3-4/3
gradient=2/3
