C - no solution
you take the second solution and times the entire equation by -1
then simply
and you get 0x + 0y = 20
Answer:
We can divide the pentagon (5 sides) into five inscribed triangles with central vertex angles of 72 degrees. 360 degrees ÷ 5 = 72 degrees....complete rotation is 360 degrees So each rotation of the pentagon of 72 degrees will be identical
Step-by-step explanation:
hope it helps :))
