Step-by-step explanation:
here,,
a=3,b=10,C=120°
c^2=a^2+b^2-2ab cos120°
=(3)^2 +(10)^2 _2 (3)(10)(-1/2) [cos120°=-1/2]
=9+100-(-30)
=109+30
=139
c=(139 )1/2=11.79
c=12
It is 23/100 just say it and then write it
The answer is C
Radius is 8.2 and circumference is 51.52
Answer:
45 feet
Step-by-step explanation:
Use ratios:

x = 540 inches
