That line is called an apothem.
In a hexagon, the side length = radius
apothem = side length / (2 * tan (180/#sides))
apothem = 8.5 / (2 * tan (180 / 6))
apothem = 8.5 /( 2 * tan (30))
apothem = 8.5 / 2 * tan (30)
apothem = 8.5 / 2 * 0.57735
apothem =

Subtract 7 to 28 = 21 then divided by -3 = x= -7
Answer:
1071/2
when you multiply the top you get 1071 and when you multiply the bottom you get 6. But if u want to simplify the answer could be 357/2
Plzzz give brainlest and thank me
-8n-25-3n then you would need too add like terms and it'd be -11n-25
Answer:A=8x^2 + 20x - 100
Step-by-step explanation:
The area of rectangle is:
A= length × width
A= (2x+10)(4x-10)
So now expand the bracket8
A=8x^2 - 20x + 40x - 100
A=8x^2 + 20x - 100
