For this case we have by definition, that the sum of the exterior angles of a polygon is equal to 360 degrees, only when considering only one exterior angle for each vertex of the polygon, regardless of the number of sides it possesses. That said we have to:
The external angle of a regular polygon is given by:
Where:
n: It is the number of sides of the polygon
Then, for a nonagon each exterior angle will measure:
Answer:
40 degrees each exterior angle
360 degrees the sum
The length of the rug is 4 ft.
The width of the rug is 2.5 ft.
Explanation:
The area of the rug is 10 ft.
The length of the rug be l.
Let us convert the inches to feet.
Thus,
Thus, the length of the rug is
Let the width of the rug be w.
Substituting these values in the formula of area of the rectangle, we get,
Solving the expression using the quadratic formula,
Substituting the values, we have,
Thus,
and
Since, the value of w cannot be negative, the value of w is 2.5ft
Thus, the width of the rug is 2.5ft
Substituting in
, we get,
Thus, the length of the rug is 4 ft.
