Answer:
I think it's uhm twelve I'm not 100% sure though
The distance between two points and can be calculated by the formula
The vertices A and B of the triangle ABC have coordinates (4,5) and (2,1), respectively.
Therefore,
Answer: correct choice is 2
Answer:
Step-by-step explanation:
As given ,
-5*(a+3) =-55
(-5*a)+(-5*3)= -55
-5a-15= -55
-5a= -55 +15
-5a = -40
a = 8
We know that
Area of a regular polygon = (1/2)*apothem<span>*perimeter
</span>perimeter <span>of the regular decagon=10*a
where
a is the length side of the decagon
in this problem
a=1.8 ft
so
</span>perimeter of the regular decagon=10*1.8----> 18 ft
Area of a regular decagon = (1/2)*2.8*18----> 25.2 ft²
<span>Round to the nearest whole number------> 25 ft</span>²
the answer is
25 ft²
