Answer:
∠ A ≅ ∠ D
Step-by-step explanation:
We have to prove Δ ABC and Δ DEF are congruent or Δ ABC ≅ Δ DEF applying the Angle-Side-Angle or ASA rule.
In order to maintain the sequence, in ASA rule we have to make congruent two angles and one side in between them.
Therefore, if ∠ B and ∠ E are proved to be congruent and segment AB and segment DE are proved to be congruent, then we have to consider another two angles which must be ∠ A and ∠ D to be congruent.
Therefore, option D is correct. (Answer)
Answer:
x = 9/2, y = -5/2
Step-by-step explanation:
5x + y = 20
10x - 2y = 50
There's multiple ways to do this, but I will solve using substitution.
Isolate variable y on the first equation.
5x + y = 20
y = 20 - 5x
Substitute the value of y for 20 - 5x in the second equation.
10x - 2(20 - 5x) = 50
Use distributive property:
10x - 40 + 10x = 50
Combine like terms:
20x - 40 = 50
20x = 90
x = 90/20
x = 9/2
Substitute x for 9/2 and solve for y:
y = 20 - 5(9/2)
y = 20 - 45/2
y = 40/2 - 45/2
y = -5/2
I’m pretty sure it’s d but ask if you need an explanation
