Answer:
10.5 ft.
Step-by-step explanation:
1. Find the radius of the larger circle
4/7 = 3/r --> the ratio should be <em>constant</em>
cross-multiplication: <em>21 = 4r</em>
Divide: <em>r = 5.25 ft.</em>
2. Find the circumference
Equation: <em>C = 2πr</em>
C = <em>2π*5.25</em>
C = 10.5π ft.
Answer:
∠A: 98 (Is a vertical angle to the 98 degrees)
∠D: 151 (180-29)
∠H: 29 (Is a vertical angle to the 29 degrees)
∠I: 29
∠J: 151
∠M: 151 (Vert angle to <J)
∠R: 82 (180-98)

Answer:
x=3
