Ierofanga [76]

Answer:

The answer is "12 inches".

Step-by-step explanation:

Please find the image file of the graph.

We know AE = CF \ and \ EB = FB so because the triangle is isosceles.

EB = 2x, FB = 2x,\ and \ CF = x when AE is called by x.

We know that AE = AD = x since E and D are tangent points to a circle.

They have CD = CF = x since D and F are tangent points only to circle.

Thus, if the perimeter is 32, the following is the result:

\to AE + EB + BF + FC + CD + DA = 32\\\\\to x + 2x + 2x + x + x + x = 32\\\\\to 8x = 32\\\\\to x = 4

Therefore the length of BC = BF + FC = 2x + x = 3x = 12\  inches

What is the value of x? Enter your answer in the box.
Radda [10]

Answer:

x=47

Step-by-step explanation:

We can use the triangle bisector theorem

TK             TV

----------- = -----------

YK               YV

Substituting what we know

87.5            77

----------- = -----------

x-22               22

Using cross products

87.5 * 22 = 77 *(x-22)

Distribute

1925  =77x - 1694

Add 1694 to each side

1925 + 1694  =77x - 1694+1694

3619 = 77x

Divide by 77

3619/77 = 77x/77

47=x

A system of equations is shown below.
Nimfa-mama [501]
-3x + 7y = -16 . . . (1)
-9x + 5y = 16 . . . .(2)

(1) x 3 => -9x + 21y = -48 . . . (3)
(2) - (3) => -16y = 64 . . . (4)

Required equivalent system of equations is
-9x + 5y = 16
-16y = 64
