given B is the midpoint of line CE, Angle C is congruent to angle E. prove angle a is congruent to angle D ​
ser-zykov [4K]

Answer:

  see below

Step-by-step explanation:

The ASA congruence postulate is being invoked, so you're looking to show two angles and the side between them are congruent.

_____

Personally, I'd go at it differently. I'd say that alternate interior angles ∠C≅∠E means AE║CD, so ∠A≅∠D because they're alternate interior angles. B does not need to be a midpoint for this proof.

Find the distance between the points (-8, -2) and (6,-1). Round your answer to the nearest hundredth.
vitfil [10]

Answer:

distance is 14.04

Step-by-step explanation:

the distance between 2 points is the Hypotenuse of the right angled triangle of the x and y coordinate differences.

we use Pythagoras

c² = a² + b²

c = the Hypotenuse (the side of the triangle opposite to the 90 degree angle).

the x difference

-8 - 6 = -14

the y difference

-2 - -1 = -1

c² = -14² + -1² = 196 + 1 = 197

c = sqrt(197) = 14.04
