Q5 Q31.) Use the Pythagorean Theorem to find the length of the missing side of the right triangle. Then find the value of each of the six trigonometric functions of theta.
Answers
Answer:
See answers in bold below
Step-by-step explanation:
Using pythagoras theorem to find the unknown side a;
c² = a²+b²
a² = c²-b²
a² = 20²-16²
a² = 400 -256
a² = 144
a = √144
a = 12
for the six trigonometry functions;
According to SOH CAH TOA
sin theta = opposite/hypotenuse
Opposite = 12
Hypotenuse = 20
sin theta = 12/20
sin theta = 3/5
cos theta = adj/hyp
cos theta = 16/20
cos theta = 4/5
tan theta = opp/adj
tan theta = 12/16
tan theta = 3/4
cosec theta = 1/sintheta
cosec theta = 1/(3/5)
cosec theta = 5/3
sec theta = 1/cos theta
sec theta = 1/(4/5)
sec theta = 5/4

Answer:
11.4 (This is already rounded to the nearest tenth)
Step-by-step explanation
1.) Add all of them
17+7+13+17+7+9+10=80
2.) Divide the sum by how many numbers there are
In this case, there are 7, so 80/7 is 11.42...
3.) Get the answer
80.7 simplifies into 11.42 so rounded to the nearest 10th is 11.4.

Gabriella answered 72 questions correctly on her multiple-choice history final and earned a grade of 36%. How many total questions were on the final exam?
Answers
Answer: 200
Step-by-step explanation: cross multiply then divide
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
If 72 questions are 36%.
36% = 72
100% = 200
The total number of questions on the final exam is 200.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
Number of questions correctly answered = 72
Percentage earned = 36%
This can be written as:
36% = 72
Now,
The total number of questions correctly answered will earn 100%.
This can be written as:
36% = 72
Multiply both sides by 100/36.
100/36 x 36% = 100/36 x 72
100% = 200
This means,
The total number of questions is 200.
Thus
If 72 questions are 36%.
The total number of questions on the final exam is 200.

Answer:
C. $126
Step-by-step explanation:
Let us say x is the amount of money Sky makes for babysitting 7 hours.
[tex]\frac{72}{4} =\frac{x}{7}[/tex]
[tex]\frac{72}{4} = 18[/tex]
[tex]18=\frac{x}{7}[/tex]

The length of Rebecca’s rectangular garden was two times the width “w”. She increased the length and width of the garden so that the area of the new garden is (2w2+7w+6)square yards. By how much did Rebecca increase the length and width of the garden. Show your complete working.
Answers
Answer:
rebecca increased the length by 3 and the width by 2
Step-by-step explanation:
First we need to find the length and width by factorizing the expressio ofr the area;
A = 2w^2+7w+6
A = 2w^2+4w+3w+6
A = 2w(w+2)+3(w+2)
A = (2w+3)(w+2)
Since l = 2w
Length = 2w+3
width = w+2
This shows that rebecca increased the length by 3 and the width by 2

Answer:
12.56ft (EDITED)
Step-by-step explanation:
the formula for circumfrence is 2 x pi x r
2 x pi x 2 = 12.57ft
C= (2)(pi)(radius)
or
C=(pi)(diameter)
But since this problem gave us the radius, we are going to use the first equation.
So our equation is:
C=(2)(3.14)(2)
Now 2 x 3.14 equals 6.28.
Now we are going to multiply 6.28 by 2. This will give us 12.56.
This means that your answer is 12.56ft.
