In the given figure , two sides of the triangle are equal , so it is isosceles triangle . So , as we know that in an isosceles triangle equal side's opposite answers are also equal . Now ,
=> x = 75°
Hence , x = 75°
Answer 2 :-Using the same property which we used in the above problem ,
• x = x
Now using angle sum property of triangle ,
=> x + x + 40° = 180°
=> 2x + 40° = 180°
=> 2x = 180° - 40°
=> 2x = 140°
=> x = 140° / 2
=> x = 70°
Hence , x = 70° .
Answer:
The ans to the first question would be 75, Coz....
It's an Isosclese triangle, as both sides are equal [The two lines on the triangle indicate that its equal]
So,the angle given is 75 degrees, the other angle would be 75 degrees too.
For the second question-
The same rule applies here, the triangle shown is an isosclese triangle,so the angle x & the angle opposite to x should be equal [The angle opposite or next to angle x is blank, so lets just call it y]
The equation of a triangle goes-
The angles of a triangle add upto 180
So 40+x+y=180
180-40 will give the sum of both angle x & y
180-40=140 [Now we know that x+y=140, we also know that both angles have the same value, so basically they're equal]
this means that we can divide 140 equally into two parts to disturbute the value to both x & y
140/2=70 degrees
So, the ans of x=70 [y is also 70, but the question doesnt ask for it]

Find the rate of change of the function by using two points from the table. Write in the simplest form.
x 2 4 6 8
y 5,8,11,14
Answers
Rate of change of given points is 3/2.
Given that
The values of x and y,
x values are 2, 4, 6, 8 and
y values are 5, 8, 11, 14.
To find
Rate of change = ...?
So, according to the question
we have,
The values of x = 2, 4, 6, 8
The values of y = 5, 8, 11, 14.
We know that,
Rate of change = (change in y )/(change in x)
= [tex]\frac{8-5}{4-2}[/tex]
= [tex]\frac{3}{2}[/tex]
The difference of other points are same, so the rate of change of given coordinates is 3/2.
Rate of change = 3/2

Ratio expresses the relationship between two or more numbers. It shows the number of times that one value is contained within other value(s).
Ratio of prism shaped blocks to pyramid shaped blocks = number of prism shaped blocks : number of pyramid shaped blocks
4 : 1
Number of pyramid blocks when there are 16 prism shaped blocks : 16 / 4 = 4
Total number of blocks : 4 + 16 = 20 blocks

Technology required. Priya starts with $50 in her bank account. She then deposits $20 each week for 12 weeks.
a. Write an equation that represents the relationship between the dollar amount in her bank account and the number of weeks of saving.
b. Graph your equation using graphing technology. Mark the point on the graph that represents the amount after 3 weeks.
c. How many weeks does it take her to have $250 in her bank account? Mark this point on the graph.
Answers
The given problem is about a person named Priya who started with $50 in her bank account and deposited $20 each week for 12 weeks. We need to find out after how many weeks she will have $250 in her bank account and also plot the given data on a graph, given that technology is required.Let's solve the given problem step by step:a) We can represent Priya's bank account after n weeks as follows:$50 + $20n
This is because she started with $50 and deposited $20 each week for n weeks.Now, to graph this equation, we can use any graphing calculator or software.
For example, we can use the Desmos Graphing Calculator, which is free and available online.To plot the given data, we need to set the domain as {0, 1, 2, 3, ..., 12} (for 12 weeks), and the range as {50, 70, 90, 110, ..., 290} (according to the equation). Then we can plot the points as follows:
After plotting the points, we can connect them with a straight line to get the graph of the equation.$$$$b)
To mark the point that represents the amount after 3 weeks, we need to find the value of the equation for n = 3, which is:$50 + $20(3) = $110This means that after 3 weeks, Priya will have $110 in her bank account.
We can mark this point on the graph as follows:$$$$$c) To find out after how many weeks Priya will have $250 in her bank account, we need to solve the following equation:$50 + $20n = $250Subtracting $50 from both sides, we get:$20n = $200Dividing both sides by $20, we get:n = 10
This means that after 10 weeks, Priya will have $250 in her bank account. We can mark this point on the graph as follows:$$$$$Therefore,
we can conclude that it will take Priya 10 weeks to have $250 in her bank account, and we can represent this data on a graph using graphing technology.

[a] Answer: y = 20x + 50
Step-by-step explanation:
We can write a linear equation to answer this part. Priya starts with $50 and adds $20 every week. Let y be the total amount of money in the bank account and x be the number of weeks passed. We will write a slope-intercept equation, where 20 is the slope and 50 is the y-intercept.
y = 20x + 50
[b] Answer: (3, 110)
Step-by-step explanation:
Next, we will use a graphing calculator as asked. Here I am using Desmos Graphing Calculator, it is free to use and online. We can type in our equation above, y = 20x + 50. See attached. Since she will not have negative weeks that she deposits, and she only deposits for 12 weeks, we will add {0 ≤ x ≤ 12} to our equation when we graph.
Since x is the number of weeks passed, 20(3) + 50 = 110, giving is the point (3, 110).
[c] Answer: 10 weeks
Step-by-step explanation:
Now, we need to find the point where she has $250 in her bank account. Since y is the total amount of money in her bank account, we can find where y = 250 on the graph.
This is at (10, 250), or 10 weeks.
