The measure of each exterior angle of a regular polygon is 30 degrees. How many sides does the polygon have

12 sides

Step-by-step explanation:

To find the number of sides, use a formula.

θ is the measure of each exterior angle of the regular polygon.

n is the number of sides of the regular polygon.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
