Answer:
Step-by-step explanation:
The sum of the angles of any polygon with 'n' sides is (n - 2) times 180 degrees.1980 / 180 = 11 , so the polygon has 13 sides and 13 angles.If the polygon is regular, then all the angles are equal.Each interior angle is 1980/13 = 152.308 degrees (rounded
Answer:
n = 13
Step-by-step explanation:
The sum of the measures of the interior angles of an n-sided polygon is
(n - 2)180
Set (n - 2)180 equal to 1980 and solve for n.
(n - 2)180 = 1980
Divide both sides by 180.
n - 2 = 11
Add 2 to both sides.
n = 13

Step-by-step explanation:
52% 2400 = 1248
48% 2400 = 1152
Reduce to 13/12 = 13:12
Multiply it out and collect terms. y = (x - 3)² + 36 y = (x² -6x +9) +36 y = x² -6x +45
