If I where you I would think of the value of a triangle then calcualate the answer, I would tell you but I don’t really know hope that helped

Step-by-step explanation:

formula : the sum of two facing inscribed angles is 180°

8x+10x=180°

18x=180°

x= 180°/18

x= 10°

2c-6+c = 180°

3c=180+6

3c=186

c=186/3

c = 62°
