The value of angle 'a' will be 40° for the given polygon.
What is a polygon?A polygon is a closed polygonal chain made up of a finite number of straight line segments and is a type of plane figure in geometry. A polygon is a region that is bounded by a bounding circuit, a bounding plane, or both.
Given that the polygon has three sides and the two angles are 56° and 84°. The value of the third angle will be calculated as:-
Angle ∠ a = 180 - 84 - 56
Angle ∠ a = 40°
Hence, the value of the angle 'a' is 40°.

What is the slope of y=-5+4xy=−5+4xy, equals, minus, 5, plus, 4, x?
Answers
Answer:
-5/4
Step-by-step explanation:
The slope of a line y=4x-5 is 4.
The equation of a line is y=-5+4x.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)
The standard form of equation of line is y=mx+c
m is a slope of a line and c is y-intercept
Compare the equation y=4x-5 with y=mx+c, we get m=4
Therefore, the slope of a line y=4x-5 is 4.

Answer:

Step-by-step explanation:
To find slope you need to take two points from the line and use the slope formula ([tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex])
Im going to take the points (0,3) and (-2,3) So now lets put these coordinates into the formula:
[tex]\frac{3 - 3}{-2 - 0}[/tex]this would give us 0
(Edit* tbh i think the line might not even exist - ya know it says ¨Find the slope of the line if it exists¨ anyway ~_~ hope this helped...!)
Answer:
Slope m=-5/3
Step-by-step explanation:
Slope is m =(y2-y1)/(x2-x1)
You need to use two points
(x1,y1)= (0,3)
(x2,y2)= (3,-2)
m=(-2-3)/(3-0) = -5/3

Answers

The solutions to the quadratic equation are:
[tex]x=i+2,\:x=-i+2[/tex]
Step-by-step explanation:
Given the equation
[tex]x^2-4x+5=0[/tex]solving the equation
[tex]x^2-4x+5=0[/tex]
subtract 5 from both sides
[tex]x^2-4x+5-5=0-5[/tex]

solving
[tex]x-2=\sqrt{-1}[/tex]
As the imaginary rule is given by
[tex]\:\sqrt{-1}=i[/tex]
so
[tex]x-2=i[/tex]
[tex]x=i+2[/tex]
solving
[tex]x-2=-\sqrt{-1}[/tex]
[tex]x-2=-i[/tex] ∵ [tex]\:\sqrt{-1}=i[/tex]
[tex]x=-i+2[/tex]
Therefore, the solutions to the quadratic equation are:

Which graph represents the solutions to this equation?
x2 + 8x = -20
Answers
Will give brainliest if correct.
Answers
Answer:
The x-intercept is 4,0. The y-intercept is 0,2.
Step-by-step explanation:
when your finding an intercept you make the other intercept 0. This means the equation to find the x-intercept would look like 5x = 20. This is because they = 0, which means 10 x 0 is 0. Then you use the inverse operation so since it's 5 * x, it will be 20 ÷ 5 which is 4. Do the same thing with the y-intercept. Instead of changing the y to a 0, change the x. Using the inverse operation you get 2.
Have a nice day!
Y-intercept = (0,2)
To find the x intercept make y = 0
5x + 10(0) = 20
5x = 20
x = 4
So (4,0)
To find the y intercept make x = 0
5(0) + 10y = 20
10y = 20
y = 2
So (0,2)

Step-by-step explanation:
Let's solve your inequality step-by-step.
x2(x+9)(x−5)≥0
x4+4x3−45x2≥0
Let's find the critical points of the inequality.
x4+4x3−45x2=0
x2(x−5)(x+9)=0(Factor left side of equation)
x2=0 or x−5=0 or x+9=0(Set factors equal to 0)
x=0 or x=5 or x=−9
Check intervals in between critical points. (Test values in the intervals to see if they work.)
x≤−9(Works in original inequality)
−9≤x≤0(Doesn't work in original inequality)
0≤x≤5(Doesn't work in original inequality)
x≥5(Works in original inequality)
