Answer
D. Angle 8
Step-by-step explanation:
Answer:
2y = 3x + 21
y = 1.5x + 10.5
plug in, in the second equation
- 4x + (1.5x + 10.5) = 23
-4x + 1.5x + 10.5 = 23
-2.5x + 10.5 = 23
-2.5x = 12.5
x = 12.5/-2.5 = -5
y = 1.5 (-5) + 10.5 = 3
x = -5
y = 3
Answer:
They are congruent.
Step-by-step explanation:
We know this for the fact that angle D and angle A are the same.
Angle B and angle A are the same
The line AB and DE are the same.
Not sure about transformations but I think it was transformed around the origin.
Not 100 percent about the last part.
Hope this helps.
