Please help me with this networks question, thank you!

Consider the following TCP connection between a sender and a receiver. You can assume that this transfer took place over a network of 10 msec of propagation delay and 1 Mbps capacity, in each direction. You can assume that the receiver has piggybacked its request with the third segment of the 3-way handshake. You can assume that the request was of 50 bytes (without headers). Only focus on TCP/IP headers and ignore the link layer headers. Answer the following questions Receiver Sender SYN seqno= 13 X1 SYNIA seqno = 121 ACK X2 01 X6 X8 AC Figure 1: Time-line Diagram (a) If segments D1, D2 D3, and D4, have the following sizes (in bytes with headers), 1000, 1000, 1000, and 500, respectively. What is the total size of the file being transferred? b) Complete the timing information (x1 through x9 Consider the following TCP connection between a sender and a receiver.
