In scalene triangle abc angle b is 45 degrees, and angle c is 55 degrees.What is the order of the sides in length from longest to shortest
Answers
The angles of a triangle always add up to 180 degrees.
A + B + C = 180
A + 45 + 55 = 180
A + 100 = 180
A = 80 degrees
The longest side is always opposite the largest angle.
Since A is the largest angle, the longest side is BC.
The next largest angle is C, and the next longest side is AB.
And the smallest angle B gives us the shortest side AC.
Therefore, your answer would be BC, AB, AC.

The correct answers are:
Top circle: 34
Bottom left: 9
Bottom right: 21
Explanation:
Let the top circle be x, let the bottom left circle be y, and the bottom right circle be z.
Following the diagram, we have the following equaitons:
x+y = 43
y+z = 30
x+z = 55
Taking the first two equations as a system, we will eliminate y:
We will subtract the bottom equation from the top:
We will now take this and the last equation as a system; this time, we will eliminate z by adding the two equations:
Divide each side by 2:
2x/2 = 68/2
x = 34
Substitute this into the first equation:
x+y = 43
34+y = 43
Subtract 34 from each side:
34+y-34 = 43-34
y = 9
Substitute this into the second equation:
y+z = 30
9+z = 30
Subtract 9 from each side:
9+z-9 = 30-9
z = 21
Final answer:
To solve this problem, assign numbers to the circles in a way that the sum of the numbers on each line is equal at both ends.
Explanation:
This question falls under the subject of Mathematics and is suitable for a Middle School grade level. To solve it, you need to find numbers for each circle such that the sum of the numbers on each line equals the sum of the numbers at each end. Let's label the circles as A, B, C, and D. The sum of A and C must equal the sum of B and D. By assigning a value to one circle, you can find the values of the other circles. For example, if A is 3, then C must be 1, and B must be 4 since B + D must equal A + C. From there, you can continue assigning values to the rest of the circles by ensuring the sums at each end are equal.

Answer:
Step-by-step explanation:
y = mx + b
Where:
y is the dependent variable (in this case, the values in the "y" column).
x is the independent variable (in this case, the values in the "x" column).
m is the slope of the line.
b is the y-intercept (the value of y when x is 0).
We can calculate the slope (m) using two points from the table. Let's use the points (3, 14) and (7, 30):
m = (y2 - y1) / (x2 - x1)
m = (30 - 14) / (7 - 3)
m = 16 / 4
m = 4
Now that we have found the slope (m), we can determine the equation:
y = 4x + b
To find the y-intercept (b), we can use one of the points from the table. Let's use the point (3, 14):
14 = 4(3) + b
14 = 12 + b
Now, solve for b:
b = 14 - 12
b = 2
So, the equation that models the relationship between x and y in the table is:
y = 4x + 2
Therefore, the correct equation is: y = 4x + 2.
