Answer:
The rotational angle of a regular polygon with 72 sides is 5º.
Step-by-step explanation:
The rotational angle (
), measured in sexagesimal degrees, of polygon of
sides is the angle of a complete revolution divided by the number of sides (
). That is:
(1)
If we know that
, the rotational angle is:


The rotational angle of a regular polygon with 72 sides is 5º.
Answer:
TU = 46
Step-by-step explanation:
Here, we are concerned with finding TU
Mathematically;
Since U is between T and B, by convention;
TB = TU + UB
Substituting the values so we can find x;
55 = 6x + 16 + 2x -1
55 = 6x + 2x + 16-1
55 = 8x + 15
8x = 55-15
8x = 40
x = 40/8
x = 5
But TU = 6x + 16; substitute the value of 5 for x
TU = 6(5) + 16
TU = 30 + 16
TU = 46
