1/3 half of it is going with the stars
Answer:
Step-by-step explanation:
Use midpoint formula to find the coordinates of each midpoint.
(x, y) = (½ (x₁ + x₂), ½(y₁ + y₂))
Coordinates of D:
(x, y) = (½ (4 + 2), ½(6 + -2))
(x, y) = (3, 2)
Coordinates of E:
(x, y) = (½ (4 + -2), ½(6 + -4))
(x, y) = (1, 1)
Slope of DE:
m = Δy / Δx
m = (2 − 1) / (3 − 1)
m = 1/2
Slope of BC:
m = Δy / Δx
m = (-2 − -4) / (2 − -2)
m = 1/2
Therefore, DE is parallel to BC.
Answer:I believe that your asnwer is c.
Step-by-step explanation:
This is because -4 + 4 = 0 10 - 10 = 0 7-7 = 0
Answer:
Communitive Property of Addition
Step-by-step explanation:
Example of Comunitive Property of Multiplecation:
a+b = b+a
There are several ways to solve this, but the law of sines is probably the easiest...
Law of Sines: sina/A=sinb/B=sinc/C for any triangle...in this case we can say:
sin48/x=sin90/55
xsin90=55sin48
x=55sin48/sin90
x≈40.873 (to nearest one-thousandth, not sure which precision you needed)
