Each side of rectangular polygon is 2.5cm in length .the perimeter of the polygon is 12.5cm. how many sides does the polygon have

There are 5 sides (a pentagon). The perimeter is the length of one side times the number of sides.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
