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.
