Answer:
9x−12
Step-by-step explanation:
The equation for a sequence is
an=a1+(n-1)d
Replace the variable with what you were given you get
37=-13+(n-1)5
Simplify
37=-13+5n-5
Combine like terms
37=5n-18
Reverse operations
55=5n
Simplify
n=11
I got it!! Ok are you ready to work on this problem???
I guess what you are asking is what is the measure of the central angle?
arc length = radius * central angle (in radians)
central angle (in radians) = arc length / radius
central angle (in radians) = 12 / 10
central angle (in radians) = 1.2 radians =
