Answer 1

Question is incomplete or wrong

Answer 2

$sum \: of \: exterior \: angles = 360 \: degrees \\ the \: measure \: of \: each \: angle \: with \: 8 \: sides = 360 \div 8 \\ \: \: \: \: \: \: \: \: = 45 \: degrees \\ with \: 9 \: sides = 360 \div 9 = 40 \: degrees \: with \: 12 \: sides = 360 \div 12 = 30 \: degrees$
