Answer:
140
Step-by-step explanation:
If it is an arc of 7pi/3, and the circumference is 6*pi or 6pi, then the arc takes up 7/18 of the circle, and since a circle has 360 degrees, the answr is 7/18 * 360 or 140.
Answer:
296 and 22
Step-by-step explanation:
111/6 = 18.5 according to the chart given, so
x/16 = 18.5.
Multiply both sides by 16 to isolate x.
x = 296
check work:
296/16 = 18.5
do the same to 407:
407/x = 18.5
Mulitply both sides by x.
407 = 18.5x
divide both sides by 18.5 to isolate x.
22 = x
check work:
407/22 = 18.5
