Answer:
(3,1)
Step-by-step explanation:
i believe this is correct
The answer would be k = -89
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
Answer:
2i^2+18i+7
Step-by-step explanation:
(5i^2+8i+10)-(3i^2-10i+3)
5i^2+8i+10-3i^2+10i-3
2i^2+18i+7
