Sheeesh that don’t look like sixth grade math to me I would help if I could sorry.
Answer:
x=121.5
Step-by-step explanation:
Angle at the center =2 times angle at the circumference
Total angle at the center =360
Angle left=360-117=243
243/2=121.5
If you look at the picture, you set it up as part over whole is equal to percent over 100. then you just multiply across.
