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
Answer:
H= 121.25 meters
Step-by-step explanation:
To find the value of H after 30 months given the equation H=0.20x+115.25,
replace x by 30 in the equation and solve;
H=(0.20*30)+115.25
H=6+115.25
H= 121.25 meters
Therefore, the height will be 121.25 meters
