We can clearly see that the triangle is an isosceles triangle. This also means that y must equal to 180 - 115. Let's solve.
=> x + y + 180 - 115 = 180=> x + y + 65 = 180Since 180 - 115 equals 65, this means that y = 65.
=> x + 65 + 65 = 180=> x + 130 = 180=> x = 180 - 130=> x = 50Conclusion:Therefore, our answers are:
x = 50°y = 65°Hoped this helped.

Answer:
Younger, superposition
Step-by-step explanation:
The first answer is younger, because for one, it's on the top of the ground sequence, and two because the second question options all prove that answer and not the "older" one.
The second answer is superposition, which states that it goes oldest to youngest from base up.

Tracy bought a can of yellow paint to use on the table and chairs in her backyard. She used 1.25 liters of paint on the chairs. She has less than 3 liters of paint left for the table.
The inequality that describes the given problem is x - 1.25 < 3.
The given parameters:
Number of paints used on the chair, = 1.25 LitersNumber of paints left for the table, less than 3 litersLet the number of liters in one can of yellow paint = x
The following inequality can be used to represent the liters of paint left for the table.
the liters of paint left = x - 1.25
The liters of paint left is less than 3 liters;
x - 1.25 < 3

How to determine if Triangles are Congruent?
If they are, how do you know if they are SSS or ASA or SAS or AAS?
Essentially, how do I apply the different congruent thermos to the questions attached?
So basically what you have to do is first identify all of the sides or angles that equal eachother then you can see if you did a side side and side in a row etc, like 44 would be SAS because the vertical angles would be inbetween the two sides. 46 would be SSS because after you make the line in the middle for reflexive property you can see that there are three sides in a row.

find the perimeter of rectangle whose length is 5m 20 cm and breadth 3.5m
Answer:
17.4 sq.mStep-by-step explanation:
Given,
Length of the rectangle = 5m 20cm = 5.2m
Breadth of the rectangle = 3.5m
Therefore,
Perimeter of the rectangle
= 2(Length + Breadth)
= 2(5.2m + 3.5m)
= 2 × 8.7m
= 17.4m
Hence,
Area of the given rectangle is 17.4 sq.m (Ans)

Answer:
I'm not 100% sure but I believe the answer is A
The total hours of work done by Laura is 39 hours.
What are Mathematical operators?A collection of numbers and operations is an expression in mathematics. The following are the parts of a math expression that do a math operation:
Operands: Operands are the numbers that an operator uses. The terms that are given to the operands vary according to the kind of operation.
Given the hourly income Laura = $14.50
total hours she works in a week = 40
increase in rate after working after 10 hours is 1.5 times
the hourly rate after 10 hours = 14.50 x 1.5 = $21.75
amount earned in 10 hours = 10 x 14.5 = $145
total earning = $775.75
the amount left after reducing the amount of 10 hours = 775.75 - 145 = $630.75
$630.75 is earned in = 630.75/21.75 hours = 29 hours
total hours Laura worked = 10 + 29 = 39 hours.
Hence Laura worked 39 hours in a week.

Step-by-step explanation:
Given x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 20 , y = 10 then
10 = 20k ( divide both sides by 20 )
[tex]\frac{10}{20}[/tex] = [tex]\frac{1}{2}[/tex] = k
y = [tex]\frac{1}{2}[/tex] x ← equation of variation → C

k=constant of variation
y= 4 when x = 10
