Answer:

See below.

Step-by-step explanation:<

< DAC and < BCA are alternate angles. So as they are congruent the 2 sides AD and BC are parallel.

Similarly as < BAC and DCA are congruent the sides AB and DC are parallel, so ABCD is a parallelogram.

Therefore as its opposite sides are congruent and AC is common to both triangles, triangle s ABC and CDA are congruent by SSS.

The following cube has a volume of 8000 cm3. Find the length of one side of the cube.

Artemon [7]

<span>Vcube = Ledge^3
8000cm^3 = Ledge^3

use the cube root of each side and you have the measure of an edge in cm.

8000^(1/3) = 20
every edge is 20 cm

20^2 = 400
The area of each face is 400 cm^2. </span>

Given:B is the midpoint of AC. Complete the statement. If AB = 7,then BC = _____, and AC = ____.

Alex73 [517]

Midpoint

We know AC is a segment and B is its midpoint. This means the length of the segment AB is half the length of the segment AC. This also means the length of the segment BC is half the length of AC, and equal to AB.

This can be visualized as follows:

Since AB=7, then BC = 7 and AC=AB+BC = 14

Answer: BC = 7, and AC=!4
