Total Area = Area of top rectangle+Area of trapezoid w/ bases 7 and 19

= base*height+(average of bases)(height of trapezoid)

= 7*4+8*(7+19)/2

= 28+104

= 132

Given AG bisects CD, IJ bisects CE, and BH bisects ED. Prove KE = FD.

OverLord2011 [107]

When a line is bisected, the line is divided into equal halves.

See below for the proof of $\mathbf{KE \cong FD}$

The given parameters are:

AC bisects CD
IJ bisects CE
BH bisects ED

By definition of segment bisection, we have:

$\mathbf{CK \cong KE}$
$\mathbf{EF \cong FD}$
$\mathbf{CE \cong ED}$

By definition of congruent segments, the above congruence equations become:

$\mathbf{CK = KE}$
$\mathbf{EF = FD}$
$\mathbf{CE = ED}$

By segment addition postulate, we have:

$\mathbf{CE = CK + KE}$
$\mathbf{ED = EF + FD}$

Substitute $\mathbf{ED = EF + FD}$ in $\mathbf{CE = ED}$

$\mathbf{CK + KE = EF + FD}$

Substitute $\mathbf{CK = KE}$ and $\mathbf{EF = FD}$

$\mathbf{KE + KE = FD + FD}$

Simplify

$\mathbf{2KE = 2FD}$

Apply division property of equality

$\mathbf{KE = FD}$

By definition of congruent segments

$\mathbf{KE \cong FD}$

Answer:

1.5

Step-by-step explanation:

(4x - 6) (2x)

= 8x^2 - 12x

8x^2 = 12x

8x = 12

In a pentagonal pyramid you have 6 vertices and 6 faces. Find the number of edges using Euler’s theorem

prohojiy [21]

Answer:

The number of edges is 10

Step-by-step explanation:

we know that

The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two

$V - E + F = 2$

we have

$V=6\\F=6\\E=?$

substitute the values

$6 - E + 6 = 2$

solve for E

$- E + 12 = 2$

$E=12-2\\E=10$
