Problem 11
Answer: Angle C and angle F
Explanation: Angle C and the 80 degree angle are vertical angles. Vertical angles are always congruent. Angle F is equal to angle C because they are alternate interior angles.
============================================
Problem 12
Answer: 100 degrees
Explanation: Solve the equation E+F = 180, where F = 80 found earlier above. You should get E = 100.
============================================
Problem 13
Answer: 80 degrees
Explanation: This was mentioned earlier in problem 11.
============================================
Problem 14
Answers: complement = 50, supplement = 140
Explanation: Complementary angles always add to 90. Supplementary angles always add to 180. An example of supplementary angles are angles E and F forming a straight line angle.
Work out the area of a circle whose diameter is equal to 14 cm.
Give your answer correct to 2 decimal places.
cm?
help
Given:
The diameter of the circle = 14 cm
To find:
The area of the circle.
Solution:
We have,
Diameter of the circle = 14 cm
We know that the radius of the circle is half of its diameter. So,
[tex]r=\dfrac{14}{2}[/tex]
[tex]r=7\text{ cm}[/tex]
The area of a circle is:
[tex]A=\pi r^2[/tex]
Substituting [tex]\pi=\dfrac{22}{7}, r=7[/tex] in the above formula, we get
[tex]A=\dfrac{22}{7}\times (7)^2[/tex]
[tex]A=22\times 7[/tex]
[tex]A=154[/tex]
Therefore, the area of the circle is 154 square cm.

how many questions out of 42 do I need to get right to score 75?
Answer:
31 questions, but it's impossible to score 75%.
Step-by-step explanation:
It's impossible to get exactly a score of 75% out of 42 questions. However, you can get the next closest percentage, which is rounded up to 74% with 31 questions right out of 75.
This is because 31 / 42 = 0.738... You can round 0.738 to 0.74. Then multiply 0.74 by 100, which gives you 74. This means the closest score you can get to 75 is 74% with 31 questions.
You can also score 76% with 32 questions right out of 42 questions. This is because 32 / 42 = 0.761... You can round 0.761 to 0.76. Then multiply 0.76 by 100, which gives you 76.

Find the scale factor from Triangle ABC to Triangle DEF.
Answer:
The ratio of any two corresponding lengths in two similar geometric figures.
Step-by-step explanation:
You can see immediately that the length of each of the sides in triangle DEF is equal to the length of the corresponding side in ABC multiplied by “a”.
If you divide the length of DE by the length of AB:
a^2/a =a.
You get a scale factor of “a”

The angle corresponding to each other of different triangle are equal.
What are similar triangle ?"Similar triangles are triangles that have the same shape, but their sizes may vary. All equilateral triangles, squares of any side lengths are examples of similar objects. In other words, if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion".
Here given,
[tex]\triangle JGR[/tex] is similar to triangle [tex]\triangle MST[/tex]
So, from the definition of similar triangle ,
angle J ≅ angle M
angle G ≅ angle S
angle R ≅ angle T
Hence, option D is correct.

Answer:
x = 46.7°
Step-by-step explanation:
We are given:
1.) Angle x
2.) Side opposite to angle x
3.) Hypotenuse
We have to find angle x, therefore Sin ratio would be used;
Sin(x) = Opposite / hypotenuse
Sin(x) = 4 / 5.5
x = Sin⁻¹(4/5.5)
x = 46.7°

Find the value of x.
Show work. please help
Answer:
x=7
Step-by-step explanation:
Since this is an isosceles triangle the two angles are equal.
3x+6 = 5x-8
Subtract 3x from each side
3x+6-3x = 5x-8-3x
6 = 2x-8
Add 8 to each side
6+8 = 2x-8+8
14 = 2x
Divide each side by 2
14/2 = 2x/2
7 = x
Answer:
x = 7
Step-by-step explanation:
Its two angle is equal so, it is isosceles triangle.
3 x + 6 = 5 x - 8 .. ( in isosceles triangle two side are equal).
3 x + 6 = 5 x - 8
Subtract 3 x from both side
3 x - 3 x + 6 = 5 x - 3 x - 8
6 = 2 x - 8
add 8 to each side
6 + 8 = 2 x - 8 + 8
14 = 2 x
Divide each side by 2
14 / 2 = 2 x / 2
7 = x

Solve for x. 4x-4< 8
AND 9x +5 > 23
is it a, b,c or d ?
Answer:
[tex] A)\displaystyle2 < x < 3[/tex]
Step-by-step explanation:
A compound inequality is an inequality that combines two simple inequalities
we are given that
[tex] \displaystyle 4x - 4 < 8 \ \: \text{and} \: \: 9x + 5 > 23[/tex]
solving x for the first equation:
[tex] \displaystyle 4x - 4 < 8[/tex]
add 4 to both sides:
[tex] \displaystyle 4x < 12[/tex]
divide both sides by 4 and since we are dividing both sides by a positive number the inequality won't swap
[tex] \displaystyle x < 3[/tex]
solving x for the second equation:
[tex] \displaystyle 9x + 5 > 23[/tex]
cancel 5 from both sides:
[tex] \displaystyle 9x > 18[/tex]
divide both sides by 9 and since we are dividing both sides by a positive number:
[tex] \displaystyle x > 2[/tex]
therefore by combining the equations we obtain:
[tex] \displaystyle\boxed{2 < x < 3}[/tex]
hence,
our answer is A)

You start at 2/3, or the left side.
Since the line is directing left, you are subtracting, or adding a negative.
If you see, you are moving 7 - 1/3s to the left
7 x 1/3 = 7 / 3
7 / 3 = 2 1/3
