umm · Answer

You good with math?

Shadow · Answer

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

umm · Answer

No, that's the full question.

Shadow · Answer

@umm What type of triangle is this?

Shadow · Answer

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.

umm · Answer

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

Shadow · Answer

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.

Shadow · Answer

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?

Shadow · Answer

Be right back, relocating :)

Legos4ver16 · Answer

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

Shadow · Answer

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

umm · Answer

@Shadow- thank you.

Are you still on here @Shadow?
