4 0

Answer:

<BCD = 128, <ECD = 52

Step-by-step explanation:

(3x + 5) + (x + 11) = 180

4x + 16 = 180

4x = 164

x = 41

<BCD is complimentary to <ACE which is (3x + 5). (3 * 41 + 5) = 128

<ECD is complimentary to <ACB which is (x + 11). (41 + 11) = 52.

The coordinates of three vertices of square ABCD are A(−212,112),B(−212,−3), and C(2,112).
Lady_Fox [76]

Answer:

<em>P=760</em>

Step-by-step explanation:

Three of the coordinates of the square ABCD are A(-212,112) B(-212,-3) C(2,112). The image below shows the square is not ABCD but ABDC. In fact, this is not a square, as we'll prove later.

Note the x-coordinate of A and B are the same. It means this side is parallel to the y-axis. Also, the y-coordinate of A and C are the same, meaning this side is parallel to the x-axis. The missing point D should have the same x-coordinate as C and y-coordinate as B, i.e. D=(2,-3).

This shape has sides that are parallel to both axes.

To calculate the perimeter we find the length of two sides.

The distance from A to B is the difference between their y-axis:

w=112-(-3)=115

The distance from A to C is the difference between their x-axis:

l=2-(-212)=215

It's evident this is not a square but a rectangle. The perimeter is

P=2w+2l=330+430

P=760

Answer: The answer is 22,452

Step-by-step explanation: Multiply 6×2 which will be 12

Put the 1 from the 12 on top of the 4 then do 4×6+1 it will equal 25

Then put the 2 on top of the 7 then do 7×6+2 it will equal 44

Then put the 4 on top of the 3 then do 3×6+4 it will equal 22
