Question

What is the length of BC?

Enter your answer in the box.

Answer 1

Since there are two angles equal to each other, this triangle is isoceles.

This means that AC = AB

Using this, we can solve for x, which also happens to be the length of BC.

2x-24=x-2
2x=x+22
x=22

So, BC is 22.

Hope this helps!

Answer 2

The length of side BC is required.

The length of side BC is 22 units.

The angles B and C are equal so triangle ABC is an isosceles triangle.

This means that the sides opposite to the angles are also equal.

So,

$2x-24=x-2$

$\Rightarrow 2x-x=-2+24$

$\Rightarrow x=22$

The length of BC is 22 units.
