The radius is √25=5 in this case.
find the area of each triangles first. (the pentagon can be divided into 5 isosceles triangles)
the two equal sides are 5 each, the angle between them is 360/5=72 degree, so the base side is 2*5*sin36, and the height is 5*Cos36
the area of each triangle is (1/2)*2*5*Sin36*5*Cos36
the total area of the 5 triangles is: 5*(1/2)*2*5*Sin36*5*Cos36
use a calculator: A≈59.44
I think it might be c. but im not sure
Well,
8 + 6q + q
We could be lazy and not simplify this. Thus, we would say:
"Eight plus 6 times a number q plus q."
Or, we could be smart, collect like terms, and say:
"Eight plus 7 times a number q."
