Prove: BC = DC.
Answers
Quadrilateral ABCD with diagonal AEC bisecting DAB, BE, DE, and 1 = 2 then BC=DC.
What is Quadrilateral?A quadrilateral is a plane figure that has four sides or edges, and also has four corners or vertices.
Given that Quadrilateral is ABCD.
diagonal AEC bisecting DAB,
BE, DE, and 1 = 2.
It is clearly given that the diagonals bisects each other.
Which means all the sides of the quadrilateral might be equal which means the quadrilateral may be a square or an rhombus.
Diagonals DAB and AEC are bisecting.
Then the sides BC and DC are equal.
BC=DC.
Hence, if Quadrilateral ABCD with diagonal AEC bisecting DAB,
BE, DE, and 1 = 2 then BC=DC.

Step-by-step explanation:
( -1, -2) and (0,4)
Slope:
m=(y2-y1)/(x2-x1)
m=(4+2)/(0+1)
m=6/1
m=6
Slope-intercept:
y - y1 = m(x - x1)
y + 2 = 6(x + 1)
y + 2 = 6x + 6
y = 6x + 4
y - 16 = 6(x - 2)
y - 16 = 6x - 12

Answers
Answer:
11.3
Step-by-step explanation:
Volume: L * W * H
L = 20
W = 8
H = 35 mm = 35/10 = 3.5 cm
V = 20 * 8 * 3.5
V = 560 cm^3
Density = m/v
Density = 6328 / 560

Step-by-step explanation:
We know that the expression is equal to 110° since it is a vertical angle. So what we do is we ad 10 to both sides of the equation. We are left with 8x=120 so if we divide 120/8 we get 15 which would leave it as x=15. Now plug it in and check it.

In a polling station, there were 900 registered voters. During an election 10% of the registered voters did not cast their votes. The rest cast their votes to Ahmed, Babu and Chambuko in the ratio 3:2:1.If 30 votes were spoilt,how many votes did Ahmed get?
Answers
Answer:
Ahmed got 390 votes
Step-by-step explanation:
Here, we want to know the number of votes obtained by Ahmed
from the question, there were 900 registered voters
10% did not cast their votes
The number that didn’t cast their votes will be;
10% of 900
= 10/100 * 900 = 90
So the rest 90% casted and this value will be 900-90 = 810
810 people casted their votes
30 votes were spoilt;
The number of valid votes is thus;
810 - 30 = 780
Ahmed got a ratio of 3 in 3:2:1
The total value here is 3 + 2 + 1 = 6
So what Ahmed got will be;
3/6 * 780
= 780/2 = 390

whats the difference between coterminal, reference, and rotational angles?
Answers
Answer:
If two angles in standard position have the same terminal side, they are called coterminal angles.
The reference angle is the acute angle (the smallest angle) formed by the terminal side of the given angle and the x-axis.
Angle of Rotation is the measurement of the amount of the angle, by which a figure is rotated counterclockwise about a fixed point, often the center of a circle. Usually clockwise rotation is called as Negative rotation
If two angles in standard position have the same terminal side, they are called coterminal angles.
What is an angle?An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.
Coterminal angles are those angles that share the terminal side of an angle occupying the standard position. The standard position means that one side of the angle is fixed along the positive x-axis, and the vertex is located at the origin.
The reference angle is the acute angle (the smallest angle) formed by the terminal side of the given angle and the x-axis.
Angle of Rotation is the measurement of the amount of the angle, by which a figure is rotated counterclockwise about a fixed point, often the center of a circle. Usually clockwise rotation is called as Negative rotation.
Hence, if two angles in standard position have the same terminal side, they are called coterminal angles.

Answer 1: x=2y−7
Answer 2: x= 3/2y -5
Heart if this helped
Answer:
x=1 and y=4
Step-by-step explanation:
Let's solve your system by substitution.
3x−6y=−21;6x−9y=−30
Step: Solve3x−6y=−21for x:
3x−6y=−21
3x−6y+6y=−21+6y(Add 6y to both sides)
3x=6y−21
x=2y−7
Substitute2y−7for x in6x−9y=−30:
6x−9y=−30
6(2y−7)−9y=−30
3y−42=−30(Simplify both sides of the equation)
3y−42+42=−30+42(Add 42 to both sides)
3y=12
y= 4
Substitute4foryinx=2y−7:
x=2y−7
x=(2)(4)−7
x=1(Simplify both sides of the equation)
