Answer 9

Four sides of square are increased further to form external angles as shown.
<2+<7=180 (supplementary angles)
<7=<6 (corresponding angles)
hence <2+<6=180 ...(1)
<8+<4=180 (adjacent angles on a straight line)
<8=<9 (corresponding angles)
Hence <9+<4=180 ....(2)

adding (1) & (2)
<2+<6+<9+<4=360
