Answer:
x can be any value (infinite number of solutions)
Step-by-step explanation:
The equation simplifies to ...
2(x -2) +3 = 2x -1
2x -4 +3 = 2x -1
2x -1 = 2x -1
This is true for every value of x. There are an infinite number of solutions.
Exterior angles of polygons always add up to 360 degrees.
A pentagon has 5 sides, so divide 360 degrees by 5 sides.
360/5 = 72
One exterior angle of a regular pentagon (all 5 sides and angles are equal) is 72 degrees.
