Answer:

  • The length of BC is 25 units.

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.
