Answer:
540°
Step-by-step explanation:
The sum of interior angles in a polygon is equal to 180(x-2) where x is the number of sides. Since there are 5 sides, 180(5-2)=540°.
Convert to vertex form:-
y = 5(x^2 - 2x) + 1
y = 5[(x - 1)^2 - 1] + 1
y = 5(x - 1)^2 - 4
vertex is (1, -4)
The perimeter is the sum of all its sides.
That is for all triangles or polygons in general.
Good luck!

The answer is c ok I just want you in my
First, factor out h so the equation can be h(b+r)=25 then divide by b+r so h= 25/b+r
