Answer:
[tex] \huge{ \boxed{ \sf{70}}}[/tex]
Step-by-step explanation:
[tex] \underline{ \sf{Given}} : [/tex]
[tex] \sf{ \angle \:FGJ \: = \: 30° \:, } \: \: \angle \: JGH \: = \: 40° \: , \: \angle \: FGH= x[/tex]
Finding the value of x°
[tex] \sf{ \angle \: FGH= \angle \: FGJ \: + \: \angle \: JGH\:}[/tex]
Plug the values
[tex] \mapsto{ \sf{x = 40 + 30}}[/tex]
Add the numbers
[tex] \mapsto{ \sf{x = 70}}[/tex]
The value of x° is 70°
Hope I helped!
Best regards! :D
