Answer:
4, obviously
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Calculate the distance d using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = D(- 4, - 3) and (x₂, y₂ ) = E(- 5, 3)
d = 
= 
= 
=
≈ 6.1 → A
Answer:
angle-angle similarity theorem
Answer:
D=7
Step-by-step explanation:
SO isolate the variable y dividing 5 on both sides
d=7
