What is BC ? Enter your answer in the box. BC= units

kumpel [21]

Answer:

The length of BC is 25 units.

Step-by-step explanation:

We know that the triangle is an isosceles triangle. Hence, we know that AB = AC. Let's first solve for x.

=> 4x + 1 = 2x + 23
=> 4x - 2x = -1 + 23
=> 2x = 22
=> x = 11

Now, let's substitute the value into the expression.

=> 3x - 8
=> 3(11) - 8
=> 33 - 8
=> 25

Hence, the length of BC is 25 units.

Hoped this helped.

2x² + 4x + 4 + x² + 1 = 180

Tasya [4]

Step-by-step explanation:

$2 {x}^{2} + 4x + 4 + {x}^{2} + 1 = 180$

$3 {x}^{2} + 4x + 5 = 180$

${3x}^{2} + 25x - 21x - 175 = 0$

$x \times (3x + 25) - 7(3x + 25) = 0$

$(3x + 25) \times (x - 7) = 0$

$3x + 25 = 0 = x - 7 = 0$

$x = - \frac{25}{3} = x = 7$

$= x_{1} = - \frac{25}{3} . \: \: x_{2} = 7$

Given: BC bisects DBE. Prove: ABD is congruent to ABE

Arada [10]

Answer:

See below

Step-by-step explanation:

BC bisects <DBE and if AC is a straight line then you have that:

<ABD + <DBC = 180 (straight angle because of line AC)

<ABE + <CBE = 180 ( straight angle because of line AC)

Because BC bisects <DBE => < DBC = <CBE

So <ABD and <ABE must be the same to both sum 180 when added < DBC
