Answer:
Arc DB = 146
x = 5
Step-by-step explanation:
Remark
The relationship between the large arc, the small arc and the intersecting angle is
1/2 (large arc - small arc) = intersecting angle.
Givens
Large arc = 25x + 21
Small arc = 96
5x
Solution
1/2*(25x + 21 - 96) = 5x*2 Multiply both sides by 2
25x + 21 - 96 = 10 x Combine
25x - 75 = 10x Subtract 25x from both sides
-75 = 10x - 25x
-15x = -75
x = 5
DB = 25x + 21
DB = 25*5 + 21
DB = 125 + 21
DB = 146

Step-by-step explanation:
Redville = r
Greenboro = 12r
Total of the two towns = 65
Now we can set up our equation.
r + 12r = 65
13r = 65
13r/13 = 65/13
r = 5
Redville gets 5 inches
It’s y=-3/4x-1 because it is
