What are the measures of Angles a, b, and c? Show your work and explain your answers.
Answers
Answer:
a= 40, b= 50, c= 115
Step-by-step explanation:
a-
There is a theorem for a that gives you the answer:
Vertical angles are congruent
If the vertical angle of a is 40°, then a is also 40°.
That is what the theorem says.
b-
This one is kind of difficult, but let me break down the steps.
Now you already know that a is 40°, and the other angle besides b is a right angle because it shows a square, or 90°.
And now you need to know another law:
Every single triangle's angle adds up to 180°.
Now, this is basically a subtraction problem.
If two of the angles are there, and you know that all of the angles of a triangle add up to 180°, then you just need to know what 90 + 40 + x = 180 is
90 + 40 = 130
130 + x = 180
Subtract 130 from both sides
130 + x = 180
-130 -130
x=50, which means that all of the angles add up to 180°, or following the law.
c-
This one is different as well.
You can very clearly see that it is a straight line that crosses 65° and c.
There is one more law as well:
A straight line is 180°.
If that line that 65 degrees and c sits on is straight, that means that-
65 + x = 180, or
180 - 65 = x
180-65 = 115, and c=115.
It also follows that law; 115 + 65 = 180, which means that it is correct.
Hope this helps :)

x = 0 is a vertical line.
If a point is reflected across a vertical line, x-value becomes the distance from the reflection line and the sign changes most likely.

After 5 minutes, the pool will hold 249,00 gallons of water.
After 20 minutes, the pool will hold 246,000 gallons of water.
After 20 minutes it will be at 246,000 gallons since 20x200=4000 and 250,000-4000= 246,000.

Youssef has $40 in his piggy bank and he spends $2 a day on a soft pretzel at lunch. Tiernan is selling his lunch each day at school to save up for an electric skateboard. After 3 days, he has a total of $22 and after 6 days he has a total of $34. In how many days will the two have the same amount of money?
Answers
Explanation:
Tiernan
10 + 4d
10 + 4(5) = 30
Youssef
40 - 2d
40-2(3) = 34
40-2(4)= 32
40-2(5) = 30
They two shall have the same amount of $30 after 5 days
[Consider "d" is number of days, "y" is total amount]
For Youssef:
Starting amount = $40Spending amount = $21) Equation created: y = 40 - 2d ____ eq(1)
For Tiernan:
3 days = $226 days = $34Unit rate: (change in amount)/(change in day) = (34 -22)/(6-3) = $4
2) Equation created:
y - 22 = 4(d - 3)y = 4d - 12 + 22y = 4d + 10 ____eq(2)For them to have same amount, solve simultaneously:
4d + 10 = 40 - 2d4d + 2d = 40 - 106d = 30d = 30/6 = 5 daysAmount after 5 days: 4(5) + 10 = $30

Make sure to enter your answer as an ordered pair. (x,y)
Answers
Answer:
(12, -23)
Step-by-step explanation:
Equate the equations:
y = y
⇒ -3x + 13 = -2x + 1
Add 3x to both sides:
⇒ -3x + 13 + 3x = -2x + 1 + 3x
⇒ 13 = 1 + x
Subtract 1 from both sides:
⇒ x = 12
Substitute x=12 into one of the equations to find y:
⇒ -2(12) + 1 = -23
Therefore, the ordered pair is (12, -23)
All you had to do was solve for x first and once you found your answer plug it in for x and then solve for y
