Step-by-step explanation:
As we know corresponding angles are equal so
6x - 100° = 2x + 4° < being corresponding angles>
6x - 2x = 100 ° + 4°
4x = 104°
x = 104° / 4
x = 26°

Step-by-step explanation:
now add up all the angles and make it equal to 180 :)
as follows
X+58+45+85 = 180
now use algebra ... and solve for X :)
X = 180-58-45-85
my calculators tells me....
X = -8

Since this is Equilateral Equiangular triangle each angle is going to be 60 degrees (sum of the interior angles of a triangle is 60 degrees).
Answer: y = 8
Step-by-step explanation:
Firstly, to solve this problem, we must identify what type of triangle this is.
This is an equalateral/equiangular triangle. This means that the sides are the same size and most importantly, the angles are the same degrees. How do we know this though? We know this because if a triangle is equilateral, it has equal angles. The reason we know this is an equilateral triangle is that it is denoted by the marks of congruency or the little dashes on the sides. All triangles that are equiangular have the same three angles of 60 degrees each. To top that off, 60 x 3 = 180, the number of degrees a triangle must have together for it to be considered a triangle. So how do we figure this out though?
Firstly, we must make the equation EQUAL to 60 degrees
60 = 8y - 4
Then simply solve
Add the 4 to each side, we need to do the reverse sign to get rid of it on the variable side. So it would be positive (+4)
60 + 4 = 8y
64 = 8y
Then, simply, we divide each side by 8 to get our answer!
64/8 = 8y/8
8 = y
y = 8
You can confirm by plugging the 8 into y, and you will get 60.

Answers
Answer:
594
Step-by-step explanation:
To find the area of a rectangle it is length * width
First break the shape into two shapes that are both rectangle
The find the length of the line on the tallest part, subtract 30 with 14
30 - 14 = 16
Lets first solve the taller one
16 * 24 = 384
Then solve the one on the left
14 * 15 = 210
Then add the both together to get the total area of the two shapes together
384 + 210 = 594

Solve with elimination
Answers
Answer:
5
Step-by-step explanation:
{
3x−y=2
2x−y=3
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
3x−y=2,2x−y=3
Subtract 2x−y=3 from 3x−y=2 by subtracting like terms on each side of the equal sign.
3x−2x−y+y=2−3
Add −y to y. Terms −y and y cancel out, leaving an equation with only one variable that can be solved.
3x−2x=2−3
Add 3x to −2x.
x=2−3
Add 2 to −3.
x=−1
Substitute −1 for x in 2x−y=3. Because the resulting equation contains only one variable, you can solve for y directly.
2(−1)−y=3
Multiply 2 times −1.
−2−y=3
Add 2 to both sides of the equation.
−y=5
Divide both sides by −1.
y=−5
The system is now solved.
x=−1,y=−5

Step-by-step explanation:
Hope this helps :)
The highest common factor (HCF) of two given numbers is 54.
What is the highest common factor?The largest number among all the common factors of the provided numbers is the GCF or HCF of two or more numbers. Their GCF is the largest integer that can be used to divide the two natural integers x and y without leaving any remainders.
The given numbers are 108 and 270.
The prime factors of the numbers 108 and 270 are
108=2×2×3×3×3
270=2×3×3×3×5
So, HCF is 2×3×3×3=54
Therefore, HCF of 108 and 270 is 54.

What is a graph?The graph is a geometrical representation of a function and can be plotted by taking x's and y's corresponding values within the interval.
For example plot of y = x³ ,y = sinx.
As per the given,
The equation of line is y = -2x² + 9x - 4
At x = 0, y = -4 so (0,-4) will be the y-intercept.
At x = 4,y = -2 x 4 + 9 x 4 - 4 = 0 so (4,0) will be x-intercept.
Hence "The x-intercept is 4 while the y-intercept is -4".
