725(2) + 900 + 10(725) = 1450 + 900 + 7250 = $ 9600 <==
interior angle of a regular 18-gon.
It is easier to calculate the exterior angle of a regular polygon of n-sides (n-gon) by the relation
exterior angle = 360/n
For a 18-gon, n=18, so exterior angle = 360/18=20 °
The value of each interior angle is therefore the supplement, or
Interior angle = 180-20=160 degrees.
Naming of a 9-gon
A polygon with 9 vertices is called a nonagon (in English) or enneagon (French ennéagone, but the English version is sometimes used)
You had a good start with the correct answer.
Exterior angle of a 15-gon
The exterior angle of a 15-gon can be calculated using the relation given in the first paragraph, namely
Exterior angle = 360/15=24 degrees
Answer:
x= 10, x=1
Step-by-step explanation:
(x-1)(x-10)=0
then solve for x
Volume of square pyramid =a²*h/3, bases are the same so area of a base =a²
Volume of cube=a²*a, same base so area of a base of a cube =a²,
because all edges of a cube are equal, so height of a cube =a
Volume of the square pyramid=Volume the a cube
a²*h/3=a²*a
h/3=a
h=3a
the height of the pyramid is 3 times the height of the cube
