They do not give us the value of angles B and C?

No, that's the full question.

@umm What type of triangle is this?

7 months ago

They give us the sides as expressions, but the important thing to notice is that two angles are congruent to each other. Two...base angles.

It's actually @Legos4ver16 question, I told her I'd help her with it, but had no idea how.

Well, if they give us that two angles of a triangle are congruent, and the third angle is not, then we can determine that this is an isosceles triangle. Isosceles triangles have the characteristic of two base angles that are congruent to each other. They also have the characteristic of the sides opposite to the base angles being considered "legs." These legs are congruent to each other.

Let me know if you understand that, and if so, tell me what this means for our problem of solving x, and thus solving for the side BC?

ok, I do understand that but I don't know what it means for our problem of solving x and the side of BC

What are the two sides opposite to our base angles (the angles that are congruent to each other) ?
