If a regular polygon has 72 sides and an order of 72,what is the polygon’s rotational angle?
Misha Larkins [42]

Answer:

The rotational angle of a regular polygon with 72 sides is 5º.

Step-by-step explanation:

The rotational angle (\theta), measured in sexagesimal degrees, of polygon of n sides is the angle of a complete revolution divided by the number of sides (n). That is:

\theta = \frac{360}{n} (1)

If we know that n = 72, the rotational angle is:

\theta = \frac{360}{72}

\theta = 5^{\circ}

The rotational angle of a regular polygon with 72 sides is 5º.

Ten percent of the reds are added to twenty percent of the blues, and the total is 24. Yet the product of the number of reds and
salantis [7]
0.10r + 0.20b = 24
3r = b + 20....b = 3r - 20

0.10r + 0.20(3r - 20) = 24
0.10r + 0.60r - 4 = 24
0.70r = 24 + 4
0.70r = 28
r = 28/0.70
r = 40 <=== there are 40 reds

0.10r + 0.20b = 24
0.10(40) + 0.20b = 24
4 + 0.20b = 24
0.20b = 24 - 4
0.20b = 20
b = 20/0.20
b = 100 <=== there are 100 blues
