The angles ∠2 = 135°, ∠3 = 135°, ∠4 = 45°, ∠5 = 45°, and ∠6 = 135° (all are in degrees)
What is an angle?Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
The angle ∠1 = 45° is given. And the diagram is shown.
Types of the angles are as follows;
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.Vertically opposite angle - When two lines intersect, then their opposite angles are equal.Alternate angle - If two lines are parallel then the third line will make z -angle and z-angles are equal angles with the parallel lines.∠1 + ∠2 = 180° (Supplementary angle)
45° + ∠2 = 180°
∠2 = 135°
∠1 = ∠5 = 45° (Corresponding angle)
∠2 = ∠6 = 45° (Corresponding angle)
∠1 = ∠4 = 135° (Alternate angle)
∠2 = ∠3 = 135° (Alternate angle)

Owen settled on a price of $7,870 for a new car. The dealer had to add 4.5% sales tax to this price, but allowed a $1,200 trade-in for Owen's old car. Although not a universal practice, please add the sales tax to the price of the new car first and then deduct the trade- in value. If the dealer required a 15% down payment, calculate the amount of the purchase price that Owen financed.
To find the amount that Owen financed, we first calculate the sales tax, add it to the initial price, deduct the trade-in value, and then calculate the percent of the final price that Owen needs to finance.
Explanation:To solve the problem, we first need to calculate the total cost of the car by adding the sales tax to the original price. Sales tax is calculated as follows: $7,870 * 4.5/100 = $354.15. So, the total cost before the trade-in is $7,870 + $354.15 = $8,224.15.
Next, we deduct the trade-in value of the old car, which is $1,200. The price after trade-in is, therefore, $8,224.15 - $1,200 = $7,024.15.
Finally, the dealer requires a 15% down payment. The amount Owen needs to finance is therefore 85% of the final price (100% - 15% = 85%). The financed amount is: $7,024.15 * 85/100 = $5,970.53.

what is the length of line segment ab
Answer:
The length of line segment is 13 units
Step-by-step explanation:
Given the line segment AB.
we have to find the length of line segment.
The coordinates of A and B are (0, 12) and (5, 0) respectively.
By distance formula,
[tex]\text{The distance between the points }A(x_1,y_1)\text{ and } B(x_2, y_2)[/tex]
[tex]AB=\sqrt{(x_2-x_1)^2+y_2-y_1)^2}[/tex]
[tex]AB=\sqrt{(5-0)^2+(0-12)^2}[/tex]
[tex]AB=\sqrt{25+144}=\sqrt{169}=13 units[/tex]
Hence, the length of line segment is 13 units.

Mrs. Jackson earned a $500 bonus s for signing a one-year contract to work as a nurse. Her salary is $22 per hour. If her first weeks checks including the bonus is $1,204, how mqny hours did Mrs. Jackson work?
To find the number of hours Mrs. Jackson worked, subtract the bonus from her total earnings and divide the result by her hourly rate. Mrs. Jackson worked 32 hours.
Explanation:To find the number of hours Mrs. Jackson worked, we need to subtract the bonus from her total earnings and divide the result by her hourly rate. Let's set up an equation:
Total earnings - Bonus = Hourly rate * Number of hours worked
$1204 - $500 = $22 * ">Number of hours worked
$704 = $22 * Number of hours worked
Divide both sides of the equation by $22:
Number of hours worked = $704/$22 = 32 hours
Therefore, Mrs. Jackson worked 32 hours.
Mrs. Jackson worked 32 hours in total.
Explanation:To calculate the number of hours Mrs. Jackson worked, we need to subtract the bonus from her total earnings and then divide the result by her hourly rate.
Let's set up an equation for this:
Total earnings - Bonus = Hourly rate * Hours worked
Substituting in the given values:
1204 - 500 = 22 * Hours worked
Simplifying the equation:
704 = 22 * Hours worked
Dividing both sides by 22 gives:
Hours worked = 704 / 22 = 32
Therefore, Mrs. Jackson worked 32 hours in total.

3x=-5y
6x-7y=17
Solve the equation
Final answer:
To solve the system of equations, we first expressed x in terms of y from the first equation and substituted it into the second equation. After simplifying, we solved for y and then substituted back into the first equation to find x. The solution is x = 5/3, y = -1.
Explanation:
To solve the system of equations 3x = -5y and 6x - 7y = 17, one can use the method of substitution or elimination. We'll use elimination for this example. First, observe that the first equation can be rewritten to solve for x in terms of y:
3x = -5y
x = -5y/3
Let's substitute this expression for x into the second equation:
6(-5y/3) - 7y = 17
-10y - 7y = 17
-17y = 17
y = -1
Now substitute y back into the first equation to find x:
3x = -5(-1)
3x = 5
x = 5/3
The solution to the system of equations is x = 5/3, y = -1.

A bird picks up a golf ball and drops it while flying 81 feet above the ground. The ball hits the top of a 32-foot-tall pine tree then bounces down to the ground. After how many seconds does the ball hit the tree?
A bird picks up a golf ball and drops it while flying 81 feet above the ground
The ball hits the top of 32 foot - tall pine tree
Now distance travelled by the ball till hitting the pine tree = 81 - 32
= 49 feet
now we have to convert feet into metre
49 feet = 14.93 metre
By applying formula s = ut + 1/2at^2
here initial velocity u = 0
And acceleration is g
therefore, 14.93 = 1/2*9.8*t^2
i.e. 14.93 = 4.9*t^2
i.e. t^2 = 14.93/4.9 = 3.047
i.e. t = 1.75 secs
Therefore ball hits the tree after 1.75 secs
Lorenzo plans to purchase three identical shirts. The shirts are on sale for 20% off. Let c represent the cost of each shirt. Which expressions can Lorenzo use to calculate his total cost for the three shirts after the discount?
Select each correct answer.
A. 0.80(3c)
B. 3c−0.20(3c)
C. 3(c−0.20c)
D. 1.20(3c)
please help
Answer:
Options A, B and C are correct choices.
Step-by-step explanation:
Let c represent the cost of each shirt.
As Lorenzo bought 3 shirts, so the cost of 3 shirts will be 3c.
We have been given that the shirts are on sale for 20% off, so the total cost of three shirts after discount will be 3c minus 20% of 3c.
We can represent this information in an equation as:
[tex]\text{Total cost for the three shirts after the discount}=3c-(\frac{20}{100}\times 3c)[/tex]
[tex]\text{Total cost for the three shirts after the discount}=3c-(0.20\times 3c)[/tex]
[tex]\text{Total cost for the three shirts after the discount}=3c-0.60c[/tex]
[tex]\text{Total cost for the three shirts after the discount}=2.40c[/tex]
Let us see our given choices one by one.
A. 0.80(3c)
Upon simplifying our given expression we will get,
[tex]0.80(3c)=2.40c[/tex]
Therefore, option A is a correct choice.
B. 3c−0.20(3c)
We have already seen that total cost of 3 shirts after discount will be 3c minus 20% of 3c and after simplifying our expression we will get,
[tex]3c-0.20(3c)=3c-0.60c=2.40c[/tex]
Therefore, option B is a correct choice as well.
C. 3(c−0.20c)
Upon simplifying our given expression we will get,
[tex]3(c-0.20c)=3c-0.60c=2.40c[/tex]
Therefore, option C is a correct choice as well.
D. 1.20(3c)
Upon simplifying our given expression we will get,
[tex]1.20(3c)=3.60c[/tex]
Since total cost of 3 shirts after discount is 2.40c, therefore, option D is not a correct choice.
