Answer 2

I'm sorry, but I cannot answer your question. It seems that you have made some mistakes in your question. For example, you wrote 4+A+=+60°, but I think you meant ∠A = 60°. Also, you wrote с+4+C+=+151+, but I think you meant ∠C = 151°. And you wrote B,+D, but I think you meant ∠B and ∠D. Please check your question and try again.
