Construct an isosceles triangle with the given base and the opposite angle to the base.
Answer:
Proof of Construction: The compass was used as a measuring tool to obtain (and copy) the length of the given segment. Since the given segment and the copy are the same length, the segments are congruent.
Note: You may also think of the length from A to B as being the radius of a circle with center at A. By copying the circle at A', the radii segments will be congruent.

You now know a lot about all the angles formed from two straight lines that intersect. You know which angles are congruent and which angles are supplementary. Based on this information, you can find the angle measurements of all the angles even when you only know the measurement of one angle. In the figure below, angle 2 measures 145 degrees. What are the measurements of angles 1, 3 and 4? A angle 1 = 35 degrees, angle 3 = 145 degrees, angle 4 = 35 degrees B angle 1 = 30 degrees, angle 3 = 30 degrees, angle 4 = 160 degrees C angle 1 = 35 degrees, angle 3 = 35 degrees, angle 4 = 145 degrees D angle 1 = 135 degrees, angle 3 = 145 degrees, angle 4 = 35 degrees
Answer:
This is the correct way to set up the equation:
9x + 88 + 6x + 182 = 180
I'm going to move some things around so we can combine like terms. It now reads:
9x + 6x + 88 + 182 = 180
9x + 6x = 15x, so the equation now reads:
15x + 88 + 182 = 180
88 + 182 = 270, so the equation reads:
15x + 270 = 180
Subtract the 270 from both sides. 180 - 270 is -90:
15x = -90
Divide both sides by 15. -90 divided by 15 = -6:
x = -6
Now we can substitute -6 back into the separate equations.
9(-6) + 88 = ?
9 times -6 is -54. -54 + 88 = 34.
6(-6) + 182 = ?
6 times -6 = -36. -36 + 182 = 146
Now we can add 34 and 146 together.
34 + 146 = 180

If the angle of R and the angle of S are vertical angles and the measure of Angle R = 39 degrees, what is the measure of angle S
Answer:
[tex]<S= 39[/tex]
Step-by-step explanation:
Verticle angles are formed when two lines intersect each other, the angles opposite each other are called verticle angles. Verticle angles are congruent, meaning their angle measures are the same. One can apply this knowledge here by stating the following,
[tex]<R\ =\ <S=39\degrees[/tex]

Jessica rented 1 video game and 3 movies for a total of $11.50.
• The video game cost $4.75 to rent.
• The movies cost the same amount each to rent.
What amount, in dollars, did Jessica pay to rent each movie?
Answer:
1 video game = 4.75
1 movie = x
4.75 + 3x = 11.50
-4.75 -4.75
______________
3x = 6.75
(3x = 6.75) ÷ 3
x = 2.25
Jessica paid $2.25 for each movie she rented.
Step-by-step explanation:
I hope this helps :)
Answer:
$2.25
Step-by-step explanation:
11.50 - 4.75 (gives you the total amount of MOVIES rented)
it's equal to 6.75 and divide that by 3 makes 2.25

Can yall tell me what B is? b-7/4=-2/3
Answer:
1 1/12
Step-by-step explanation:
b-7/4=-2/3
First, in an equation like this, you add 7/4 to each side which will look like this:
b-7/4=-2/3
+7/4=+7/4
We add 7/4 to each side of the equation to balance the numbers.
b=+7/4-2/3 (because the minus symbol is in front, we put that)
Before adding we have to find the least common denominator known as LCD.
We find that by first looking at the denominators or the fractions which are 4,3
4,8,\12/,16,20,24.
3,6,9,\12/,15,18,21,24.
We can also find the LCD by multiplying 3 and 4. As you can see in the list, there are 12's in each list of numbers. We use that to change our fractions.
From the number 4 we find out how many times (x) we have to add 4 to get 12. We do 12/4 which is 3. And 12/3 which is 4.
7 x 3 2 x 4
------- - -------
4 x 3 3 x 4
which equals 21/12-8/12. Now that we have a common denominator, we can subtract.
21 8 13
--- - --- = ----- = 1 [tex]\frac{1}{12}[/tex]
12 12 12

7. An administrator surveys a random sample of 48 out of 900 middle school students. Using the
survey results, the administrator predicts that 225 students are in favor of the new dress code.
How many of the 48 students surveyed were in favor of the new dress code?
Answer:
12 students
Step-by-step explanation:
225 is 25% of 900 and 25% of 48 is 12.
The number of students is 12 that is surveyed were in favor of the new dress code the answer is 12.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
An administrator surveys a random sample of 48 out of 900 middle school students.
Using the survey results, the administrator predicts that 225 students are in favor of the new dress code.
The proportion of sample = 225/900
= 0.25
In percent sample:
= 0.25x100 %
= 25%
A number of students surveyed were in favor of the new dress code:
= 25% of 48
= (25x48)/100
= 1200/100
= 12
Thus, the number of students is 12 that is surveyed were in favor of the new dress code the answer is 12.
