Please help me I need help with my test review I can’t figure out m<1 and m<2

Answer:
m1=12 and m2=168
Step-by-step explanation:
[tex] m1 + m2 = 180 \: (straight \: angle) \\ then \\ x - 12 + 7x = 180 \\ 8x - 12 = 180 \\ 8x = 180 + 12 = 192 \\ x = 192\div 8 \\ x = 24\\ hence \\ m1 = 24 - 12 = 12 \\ m2 = 7 \times 24 = 168.[/tex]
