The formula to find the interior angles is :
(n-2)×180°
Wheras n=the number of sides.
Angles sum of 25-gon therefore will be:
(25-2)×180°
=4140°
Thus,4140° is the answer.
Hope it helps!
3,000 = 3 x 10 x 10 x 10 = 3 * 10^3
--------------
10^3 * 3 * (640)
= 10^3 * 3 * (600 + 40)
= 10^3 * (1800 + 120)
= 10^3 * 1920
= 1,920,000
No.
62 + 9
when broken apart will look like
60 + 2 + 9
for 62 = 60 + 2
hope this helps
Answer:
about 748.2 ft^2
Step-by-step explanation:
We can break up the hexagon of side length 12 into 6 congruent equilateral triangles of side lengths 12. Thus by finding the area of 1, we can multiply it by 6 to get the area of the hexagon.
Formula for area of equilateral triangle: ((side^2)√3)/4
We plug in the side as 12, and we get 72√3
We then multiply by 6 to get the approximate answer of 748.2 ft^2

Answer:
x = 35, x = 27
Step-by-step explanation:
(9)
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
141° is an exterior angle, thus
x + 24 + 2x + 12 = 141 , that is
3x + 36 = 141 ( subtract 36 from both sides )
3x = 105 ( divide both sides by 3 )
x = 35
-----------------------------------------------------------
(11)
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
2x - 9 + 3x + 2x = 180
7x - 9 = 180 ( add 9 to both sides )
7x = 189 ( divide both sides by 7 )
x = 27
