Answer:

Step-by-step explanation:
The length of any arc is calculated using the following equation:
s = r*θ
Where s is the length of the arc, r is the radius of the circle and θ is the angle in radians.
So, if we have a Circle O and a centrally angle AOB that measures π/3 radians, the value of the length of arc AB is calculated as:

Where r is the radius of the circle O.

Answer:
-7
Step-by-step explanation:
-2(x+5)=4
open the bracket with -2
-2x - 10 = 4
combine the like terms
-2x = 4 + 10
-2x = 14
divide by -2
-2x/-2 = 14/-2
x = -7
