I believe this situation pertains to "two individuals," though I consider a 16-inch pizza to be more than sufficient. Apologies if I'm mistaken.
Answer:
The measure of arc GH is 80 degrees.
Step-by-step explanation:
Circles F and J are congruent.

Given that: m∠DFE = 80°
Angle DFE serves as the central angle of circle F.
Arc GH's measurement corresponds with the central angle from Circle J.
Since the two circles are congruent

The measure of arc GH, therefore, is 80 degrees.
Answer:
7040
Step-by-step explanation:
C= 2000
B = 20/100 x 2000 = 400 + 2000 = 2400
A= 10/100 x 2400 = 240+2400= 2640
2000 + 2400 + 2640 = 7040
