Answer:
x=11
Step-by-step explanation:
We know that the angle is equal to 1/2 the difference of the long arc length between where the line segments touch the circle and the small arc length where the line segments touch the circle
They long distance is 360 - (86+74) = 200
The small distance is 86
4x+13 = 1/2 ( 200 - 86)
4x+13 = 1/2 (114)
4x+13 = 57
Subtract 13 from each side
4x+13-13 = 57-13
4x= 44
Divide by 4
4x/4 = 44/4
x=11
A formula is recursive if it expresses the term
in terms of the previous one(s) 
In this case, every term is 7 more than the previous one, so the formula for
will only involve
:

In fact, this formula is simply saying: for every index
, the term with that index is 7 more than the term before.
Also, we have to specify the starting point (otherwise we would go backwards indefinitely), so the complete recursive formula is

which means: start with 2 and generate every other term by adding 7 to the previous one.
Both the pies at first have 360* as their initial complete angles.
The Cherry Pie is cut into 6 parts equal and the angular width of each piece will be 360/6=60*...therefore, each piece is 60*.
the Apple Pie is cut into 8 parts and the angle of each piece would be 360/8=45*...therefore, each piece is 45*.
Now the angular difference between the pieces of the 2 pies is 60*-45* = 15*.
Therefore the Cherry pie's piece is 15* greater than the Apple pie's piece.
24 miles is 1 gallon so 360 miles is 15 gallons + 24 is 384 miles so they are not equivalent!
