Answer:
so first we will find the interior angle:
1 angle : 31 (given )
2 angle :31 ( the base angles of isoscles triangle are equal)
3 angle : 31 + 31 + x = 180 ( angle sum property of triangle)
x = 180 - 62 = 118
now the exterior angles :
1 angle : 180 - 31 = 149 ( exterior angle and the angle adjacent usually forms a line (= 180) )
2 angle : 149 ( same reason as the first)
3 angle : 180 - 118 = 62 ( same reason as the first)
( i dont know if there is any other way, but this is one)
Decide whether enough information is given to prove that the triangles are congruent. If so, state the theorem you would use
not enough information provided
yes; AAS Congruence Theorem
yes; SAS Congruence Theorem
yes; SSS Congruence Theorem
Answer:
Yes; AAS Congruence Theorem
Proof:
In [tex]\triangle ABC[/tex] and [tex]\triangle QRS[/tex]:
[tex]\angle BAC = \angle RQS[/tex] (given)
[tex]\angle ABC = \angle QRS[/tex] (given)
[tex]AC =QS[/tex] (given)
∴ [tex]\triangle ABC \cong \triangle QRS[/tex] (AAS)
There is enough information to prove that the two triangles are congruent through the AAS congruence theorem.
Hope this helps :)
Name the additive identity of (-10+4i)
An additive identity for i, denoted e, is an element in i such that for any element i in i, e + i = i = i + e. Example: The formula is i + 0 = i = 0 + i.
The additive identity of (-10+4i) is (0+0i).
What is additive identity?Additive identity property states that when a number is added to zero will give the same number in result . “Zero” is called the identity element, If we add any complex number with zero, the resulting number will be the same complex number. It doesn't change the number and keeps its identity.
For the given situation,
The complex number is (-10+4i)
The general form of complex number is a+bi. The additive identity for complex number is 0+0i.
⇒ [tex](-10+4i)+(0+0i)=(-10+4i)[/tex]
Hence we can conclude that (0+0i) is the additive identity of (-10+4i).

Cory is a bird watcher he estimates that 30% of the birds he sees are american robins, 20% are dark eyed juncos and 20% are slnc sparrows. he designs a simulation.
Answer:
I think C. 0.75
Step-by-step explanation:
The probability of seeing at least one robin in the next 5 birds is 0.75
How to determine the probability?The representations are given as:
American robins = 0 to 2Dark eye juncos = 3 and 4Song sparrows = 5 and 6Others = 7 to 9Using the above representations, the numbers that represent an occurrence of seeing at least one robin in the next 5 birds are:
05716 16803 32177 92290 72794 14333 79019 05943 77510 74051 87238 86481 94036 12749 24005
The number of occurrence is:
Number = 15
The number of simulation is 20
So, the probability of seeing at least one robin is:
P = 15/20
Divide
P = 0.75
Hence, the probability of seeing at least one robin is 0.75

On one particular day, Jamal arrived late to find four other co-workers waiting for him to arrive. They were unable to do other work because they had made arrangements to have their position covered and to work with Jamal on a special project. Nothing could be done until he got there. The other workers earned wages as followed: Derek earns $10.00/hr; Sam earns $11.80/hr; Penny earns $11.00/hr and Zachary earns $13.00/hr. How much was lost in unproductive wages because Jamal arrived 15 minutes late?
Answer: $11.45
Step-by-step explanation:
Arriving 15minutes late simply means 15/60 = 1/4 of the wages has been lost. We then multiply 1/4 by each person's wage. This will be:
Derek = 1/4 × $10.00
= $2.50
Sam = 1/4 × $11.80
= $2.95
Penny = 1/4 × $11.00
= $2.75
Zachary = 1/4 × $13.00
= $3.25
The amount lost will be:
= $2.50 + $2.95 + $2.75 + $3.25
= $11.45

Step-by-step explanation:
PQR = PRQ = 2x ° ( base angle of an isosceles are equal ) .
therefore
PQR + PRQ + QPR = 180° ( sum of angles in a triangle )
2x + 2x + 40 = 180
4x + 40 = 180
subtract 40 from both sides
4x = 140
divide through by 4
x = 35°

A photography studio charges $50 for a sitting fee and 6 prints. Luigi increased his order to 11 prints and paid $65. Write an equation in point-slope form.
HELP ME PLEASEEEE!!!
Answer: Sitting fee - 32$
Step-by-step explanation:
This is a system of equations(let x represent the sitting fee)
x+6y=50
x+11y=65
You want to isolate the x variable - x+6y-6y=50-6y ; x = 50-6y
Input this into the 2nd equation: 50-6y+11y=65 ; 50+5y=65
Subtract 50 from both sides. 5y=15 (Divided 5y on both sides) ; y=3
Now that y = 3 input this into any equation I choose the 1st one.
x+6(3) = 50 ; x + 18 = 50 (Subtract 18 on both sides to get x)
x = 32
Prove: 32 + 6(3) = 50 ; 32+18 = 50 ; 50 = 50 True

Please help me will give brainillest is work is shown. thank you !!!
9514 1404 393
Answer:
see attached
Step-by-step explanation:
For values of x less than zero, the graph of the function is a graph of the line
y = -x
Because the function is defined by this expression at x=0, there will be a solid dot at the end of the line there, at (0, 0).
__
For values of x greater than 0, the graph of the function is a graph of the line
y = -x -2
This line has the same -1 slope as before, but has a y-intercept of -2. The function is not actually defined as (0, -2), so there is an open circle at the end of the line there.

rocky thinks of an odd integer adds the next two consecutive integer which of these could be the sum
Answer:
C
Step-by-step explanation:
1. Let x be the odd integer. Let y be the sum.
x + (x + 1) + (x + 2) = y
3x + 3 = y
Adding two consecutive integers to an odd integer will result in an even integer.
So, you can eliminate choices B and D since they are odd.
Lastly, plug in choices A and C for y and choose the answer that makes x an integer.
Choice C would give you the correct result.
3x + 3 = 44562
3x = 44559
x = 14853
The odd integer and the two consecutive integers whose sum is 44,562 are 14,853, 14,854, and 14,855 respectively.
Let
Small odd integer = xNext consecutive integer = x + 1Next two consecutive integer = x + 2Sum of consecutive integers = 44,562Sum:
x + (x + 1) + (x + 2) = 44,562
x + x + 1 + x + 2 = 44, 562
3x + 3 = 44,562
Subtract 3 from both sides3x = 44,562 - 3
3x = 44,559
divide both sides by 3x = 44,559 / 3
x = 14,853
Therefore, the odd integer and the two consecutive integers whose sum is 44,562 are 14,853, 14,854, and 14,855 respectively.

Answer:

Step-by-step explanation:
Since the smaller triangles have a side of the same length, they share one side, and the included angle is 90°, the triangles are congruent.
This means the length of the side to the left is also x as shown in the image below.
The bigger triangle is also right and has side lengths of x, x, and 6 (the hypotenuse), thus:
[tex]x^2+x^2=6^2[/tex]
