What is the angle of rotation about the center that will map the regular pentagon onto itself
Andrew [12]

The answer is 180 degrees. The rotation that maps one side to an adjacent side is 360°/6 = 60°. This is the least rotation that plots the regular hexagon to the aforementioned. In the least whole number of these minimum rotations, such as three 60° rotations to make 180°, will retain the hexagon identical.

Solve each equation by completing the square NEED THIS IN 10 MINS WILL GIVE BRAINLIEST
yulyashka [42]

Answer:

Step-by-step explanation:

7(b² - 2b - 8) = 0

7(b² - 2b +   ) = 8

7(b² - 2b + 1) = 8 + 1

7(b - 1)² = 9

(b - 1)² = 9/7

b - 1 = ±√(9/7)

b = 1 ±3√(1/7)

b ≈ -0.134, 2.134

m² + 10m + 14  = -7

m² + 10m +      = -7 - 14

m² + 10m + 25 = -7 - 14 + 25

(m + 5)² = 4

m + 5 = 2

m = -3

p² - 8p + 21 = 6

p² - 8p +     = 6 -21

p² - 8p + 16 = 6 -21 + 16

(p - 4)² = 1

p - 4 = 1

p = 5
