Answer:

{10,8}

Step-by-step explanation:

-3x + 4y = -62

4x + 5y = 0

let's eliminate the x

-3x + 4y = -62 | x -4 |

4x + 5y = 0 | x 3 |

12x - 16y = 248

12x + 15y = 0

-------------------- -

-31y = 248

y = 248/(-31) = 8

since you must do this proble with elimination, we cant use subtitution. so we repeat the way once more to find x (eliminate y)

-3x + 4y = -62 | x 5 |

4x + 5y = 0 | x 4 |

-15x + 20y = -310

16x + 20y = 0

-------------------- -

-31x = -310

x = -310/-31 = 10

Compute and compare the side lengths of the two figures. Does this support an argument claiming that they are congruent? What el
Sunny_sXe [5.5K]
We compute for the side lengths using the distance formula √[(x₂-x₁)²+(y₂-y₁)²].

AB = √[(-7--5)²+(4-7)²] = √13
A'B' = √[(-9--7)²+(0-3)²] = √13

BC = √[(-5--3)²+(7-4)²] = √13
B'C' = √[(-7--5)²+(3-0)²] =√13

CD = √[(-3--5)²+(4-1)²] = √13
C'D' = √[(-5--7)²+(0--3)²] = √13

DA = √[(-5--7)²+(1-4)²] = √13
D'A' = √[(-7--9)²+(-3-0)²] = √13

The two polygons are squares with the same side lengths. 

But this is not enough information to support the argument that the two figures are congruent. In order for the two to be congruent, they must satisfy all conditions: 
1. They have the same number of sides.
2. All the corresponding sides have equal length.
3. All the corresponding interior angles have the same measurements.

The third condition was not proven.

Answer: A=20.8, B=20.5, C=10, D=2, E=12.6

Explanation: It takes time, but all you have to do it make an equation adding all the sides together, which equals 85.9. Then find “a” and plug that back in to each side. (I’m pretty sure this is right, but sorry if I’m wrong)
