Answer:
[tex]m\angle FGC =101\degree [/tex]
Step-by-step explanation:
[tex]m\angle CBF = 46\degree[/tex] (Given)
[tex]m\angle FIG = 55\degree[/tex] (Given)
[tex]m\angle IFG = m\angle CBF[/tex] (Corresponding angles)
[tex]\implies m\angle IFG = 46\degree[/tex]
[tex]m\angle FGC =m\angle IFG+ m\angle FIG[/tex]
(By exterior angle theorem)
[tex]m\angle FGC =46\degree+ 55\degree [/tex]
[tex]m\angle FGC =101\degree[/tex]
