Help with a question-2

In the dedicated geometry Exercise-8 can you please explain the answer? I am seriously stuck with that question.

Thanks,
Prakhar

Well what’s the question?

Thanks for your reply. I got it now. It was a similar triangle question in a Dedicated Geometry I video given as a homework.

Also, can you please share with me the video/document where I can study SIMILAR TRIANGLES concepts.

Thanks,
Prakhar
