What is the sum of the exterior angles of a polygon that has 67 sides

67 angles

Step-by-step explanation:

A triangle has 3 sides and 3 angles. A pentagon has 5 sides and five angles. This pattern repeats on and on forever. At 67 sides, you get 67 angles.

picture below

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
