Answer:

Perimeter is 35 units.

Step-by-step explanation:

A heptagon has 7 equal sides.

Given the length of two consecutive vertices, A(-2-5) and B(1,-9).

We can find the length of AB and multiply by 7.

Recall the distance formula;

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

The length of AB is

|AB|=\sqrt{(-2-1)^2+(-5--9)^2}

|AB|=\sqrt{(-3)^2+(4)^2}

\Rightarrow |AB|=\sqrt{9+16}

\Rightarrow |AB|=\sqrt{25}

\Rightarrow |AB|=5\:units

Therefore the perimeter is 7\times 5=35\:units.

Determine 2 coterminal angles in radians for 7pi/2
bija089 [108]
Check the picture below.

notice, that one go-around is 2π, or namely 4π/2, and if we go 3π/2 more over, we'd end up at at 4π/2 + 3π/2 or 7π/2.

a couple of coterminal angles will be those in blue, one angle in the first go-around, and another one by simply going around one more time by 4π/2 extra, 7π/2 + 4π/2 is just that one there.
