Answer: 110 degrees
Since the 2 unknown angles in the triangle are equal you do (180-40)/2 to find what they are equal to. (It's equal to 70) Now that you have the answer for the two angles, now you can subtract 70 from 180 which gives you 110 degrees and that's your answer
Hope this helped you!
Answer:
x°+x°+40°=180°
2x°=180°-40°
2x°=140°
x°=140°
2
x°=70°
x°=70°
therefore,
x=180°-70°
x°=110°

Step-by-step explanation:
First, note you can remove the brackets, in this case they contribute nothing at all.
Then, group the like terms and add them, e.g., we have 3r³ and -2r², they add up to r³.
Finally, order them from greatest power of r to smallest power of r.

I am not sure why, but I think it’s that a parallelogram has diagonals of equal length on opposite sides, hence “parallelogram”.
Knowing any two (out of the four) sides of a parallelogram, the other sides can be drawn accurately.

coefficients and constants of the expression. What error might Jake have made? (Used, two separate answers as needed)
Answers
Answer:
Jake doesn't include 1 as constant.
Step-by-step explanation:
The given expression is 6+n+5b.
Jake says that 5 is a coefficient and 6 is a constant.
In this case, the coefficient is 5.
Constants are 6 and 1.
And variables are n and b.
Hence, Jake doesn't include 1 as constant.

-2x + 2y = 2 4x –4y= 4A.No solutionB.One solution: x = _____ y = ___C.Infinitely many solutionsBONUS: A customer at a concession stand bought 2 boxes of popcorn and 3 drinks for $12. Another customerbought 3 boxes of popcorn and 5 drinks for $19. How much does a box of popcorn cost? _____________How much does a drink cost?__________________
Answers
Answer:
See answers below
Step-by-step explanation:
1) Given the simultaneous equation;
-2x + 2y = 2 .... 1 * 2
4x –4y= 4...2 * 1
____________
-4x + 4y = 4 .... 1
4x –4y= 4...2
Add both equations
4y-4y = 4-4
0y = 0
y = 0/0
Let x = k
Substitute x = k into 1
From 1: -2x + 2y = 2
-x+y = 1
-k + y = 1
y = 1+k
Hence the solution to the system of equation (x, y) is (k, 1 + k) where k is any integer.
The presence of k shows that the equation has many solutions since k can take any value
2) Let a box of popcorn be x
Let the cost of a drink be y
If a customer at a concession stand bought 2 boxes of popcorn and 3 drinks for $12, then;
2x + 3y = 12 ... 1
Also, if another customer bought 3 boxes of popcorn and 5 drinks for $19, then;
3x + 5y = 19 ...2
Solve 1 and 2 simultaneously
2x + 3y = 12 ... 1 * 3
3x + 5y = 19 ...2 * 2
_________________
6x + 9y = 36
6x + 10y = 38
Subtract
9y - 10y = 36 - 38
-y = -2
y = 2
Recall that 2x + 3y = 12
2x + 3(2) = 12
2x + 6 = 12
2x = 12-6
2x = 6
x = 6/2
x= 3
Hence a box of popcorn cost $3 and a drink cost $2
Solve the system by substitution.

The measures of the exterior angles of an octagon are x°, 2x°, 4xº, 5x°, 6x°, 8xº,
9x", and 10x°. Find the measure of the smallest exterior angle.
Answers
Answer:
8°
Step-by-step explanation:
The sum of the measures of the exterior angles of a any polygon = 360.
So, x + 2x + 4x + 5x + 6x + 8x + 9x + 10x = 360
45x = 360
x = 8°
The measure of the smallest exterior angle would be equal to 8°
What is Octagon ?In geometry, a Octagon is a eight - sided polygon. For a [n] sided polygon -
Sum of interior angles = (n - 2) × 180°Each interior angle of a regular polygon = [(n − 2) × 180°/n]Sum of exterior angles = 360°According to the question, we have - A Octagon and the measures of the exterior angles of an octagon are x°, 2x°, 4x°, 5x°, 6x°, 8x°, 9x° and 10x°.
The sum of the exterior angles of the octagon will be 360°.
Therefore, we can write -
x + 2x + 4x + 5x + 6x + 8x + 9x + 10x = 360°
45x = 360°
x = 360/45
x = 8
The smallest exterior angle would be equal to [x]° = 8°
Therefore, the measure of the smallest exterior angle would be equal to 8°

Find the coordinates of the circumcenter of the triangle with the vertices A (4, 12), B (14, 6), and C (-6, 2)
Answers
Answer:
Step-by-step explanation:
Determine the perpendicular bisector of AB:
Slope of AB = (12-6)/(4-14) = -0.6
Midpoint of AB: ((4+14)/2, (12+6)/2) = (9, 9)
Perpendicular bisector: y = -0.6x + 14.4
Determine the perpendicular bisector of AC:
Slope of AC = (12-2)/(4+6) = 1
Midpoint of AC: ((4-6)/2, (12+2)/2) = (-1, 7)
Perpendicular bisector: y = x + 8
Circumcenter is the intersection of the perpendicular bisectors.
x + 8 = -0.6x + 14.4
1.6x = 6.4
x = 4
y = x + 8 = 12
