First 2 triangles can be proven similar but are not necessarily congruent since you can't from them using the side-angle-side or angle-side-angle or triple side rule.
2)
ONM = QNP since they are vertically opposite angles.
MON = NPQ given equal on the figure
ON=NP given
The two triangles are proven congruent using the angle-side-angle property.

Angles A and B are complementary to each other. If mA = 130 + x and mB = 170 + x, what is the value of x?∠∠
Answers
Answer:
-105
Step-by-step explanation:
This means their measures add to 90 degrees, so:
(130+x)+(170+x)=90
300+2x=90
2x=-210
x=-105
The value of x in the expression for the measure of the complementary angle is -105.
What is the numerical value of x?Complementary angles are simply angles that sum up to 90 degrees.
Given the parameter:
Angles A and B are complementary.
Measure of angle A = 130 + x
Measure of angle B = 170 + x
Value of x =?
Since angles A and B are complementary, their sum should be equal to 90 degrees.
Hence:
Angles A + Angle B = 90
Plug in the expressions:
(130 + x) + (170 + x) = 90
Combine like terms:
x + x + 130 + 170
2x + 300 = 90
Subtract 300 from both sides:
2x + 300 - 300 = 90 - 300
2x = -210
x = -210/2
x = -105
Therefore, x has a value of -105.

Answers
Answer:
the answer is d) y = cos(x - Pi) - 2
Step-by-step explanation:
you can see that on the graph that os must be -2.. so you can move it for 2 up
than you have to take in count that (x - Pi) so you move your graph for Pi to the left
and than you have to recognize the function.. if it goes through 0 is sin if not is cos
The equation for the graph y = cos(x - Pi) - 2.
You can see that on the graph that os must be -2.
So you can move it for 2 up.
What is the meaning of the graph?
A graph is a mathematical diagram that shows the relationship between two or more sets of numbers or measurements.
Then you have to take into count that (x - Pi).
So you move your graph for Pi to the left
Then you have to recognize the function.

1. Mrs. Galicia is building a chicken farm in 2021 with an initial population of 3750 chickens. The farm grows at a rate of 2.15% annually.
(a) Use the exponential growth model to write an equation that estimates the population t years after 2021.
(b) Estimate the population of the town in 2036. *please show plug in step*
Answers
Hey there!
a) --›initial number = 3750
--›rate = 2.5%
let y be the population t years after 2021
So, y = 3750(1+2.15) ^ t
=> 3750 × 1.0215 ^ t
b) In 2036,
=> t = 2036 - 2021
=> 15
Substitute into the first value
=> 3750 × 1.0215 ^ t
=> 3750 × 1.0215 ^ 15
=> 5159.
Therefore, the population in 2036 would be 5159

Assume that based on 2,000 calories per day, you want to choose 1/8 of your daily calories from consuming milk. How many calories am I allowed to get from milk and how many cups per serving?(1 cup of milk has 150 calories)
Answers
Answer:
1.7 cups
Step-by-step explanation:
Firstly, we need to figure out how many calories of milk we are allowed to consume. This would be solved by dividing 2000 by 8 to find 1/8 of 2000.2000 ÷ 8 is 250 calories. With this information, now we can use the information we have about one cup of milk.If one cup of milk is 150 calories and we are allowed to consume 250 calories of milk, we can solve by dividing 250 by 150.250 ÷ 150 is 1.7 cups of milk.If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers.

Breaking Even on Pizza
Suppose the student organization you are apart of has decided to hold a pizza fund-raiser during finals week. Sure we have Cost + Markup = Selling Price, but this sounds more like Pizza + Finals = Success. Your club plans to purchase 50 pizzas and resell them in the student center. For your initial post, I'm hoping you'll get creative: tell us about your student group (and yes, you can make up one that you think you' be apart of).
Next, choose a pizza store to purchase from. You can purchase from somewhere local, or you can choose a chain as well. Research their current promotions on pizzas and find the cost per pizza (you can decide what size of pizzas to purchase since specials will vary). It probably makes sense to explain why you made the choice you did. How much will it cost to purchase 50 pizzas?
Lastly, calculate what you would need to charge per slice to break even. In other words, if you only wanted to sell pizza and not make a profit, what would you charge for each slice?
For your first reply post, reply to your own post. Since this is a fund-raiser, what would you suggest charging for each slice and, based on this, what would the percent markup be? Also, what would the net profit be if you sold all 50 pizzas?
For your second reply post, reply to someone else's post and decide if their cost per slice is too high. Would you pay that much for a slice of pizza? Suppose they only sold 40 pizzas. Will they still make a profit? Will they break even? If you think they should adjust the cost per slice, explain why.

Answer:
75 degrees and 105 degrees.
Step-by-step explanation:
So this is a transversal. We can use a couple different methods to solve this. We can use many different theorems to solve this problem. So we know that m<2=m<4 because of vertical angles, we also know that m<4=m<6 because of alternate interior angles. We also know that m<6=m<8 because of vertical angles. So we know that m<2=m<4=m<6=<8. In a transversal, there are only two different measurements. And those two different measurements add up to 180 degrees. So since once of the measurements is 75, that means the other measurement has to be 105 degrees. Also, we see that m<4 and m<5 are same side interior angles and according to that theorem, they have to equal up to 180 degrees.

For a craft project, Lisa needs 12 pieces of material that are 6.45 inches wide. What is the total width of material that Lisa will need to buy?
Answers
The total width of the craft project is an illustration of products
The total width is 77.4 inches
How to determine the total width?The given parameters are:
Number of pieces = 12
Width of each piece = 6.45
The total width is the product of the number of pieces and the width of each piece.
So, we have:
Total = 12 * 6.45 in
Evaluate
Total = 77.4 in
Hence, the total width is 77.4 inches
