Given: triangle ABC is isosceles
This tells us that the triangle has two equal sides.

Target question: What is the length of side BC?
When I scan the two statements, they both feel insufficient, AND I’m pretty sure I can identify some cases with conflicting answers to the target question. So, I’m going to head straight to……

Statements 1 and 2 combined
Here are two triangles that satisfy BOTH statements:
Case a: The triangle could look like this:

In this case, the answer to the target question is side BC has length 4

Case b: The triangle could also look like this:

In this case, the answer to the target question is side BC has length 4√2

Since we can't answer the target question with certainty, the combined statements are NOT SUFFICIENT

Answer: E

I'll check again but I doubt it as I am able to see the attached images of other posts. Maybe you could post the images again in a different format ? Would be of great help.

Sounds like an issue with your computer. So, I can't really help you.
I assume you've tried restarting it.
