Answer:
$19.49
Step-by-step explanation:
48.2 - 29.6 = 18.6
18.6 + 0.89 = 19.49
I think the answer is -3/2
In this problem we need to find the apothem and the length of the side before we can find the area of the entire polygon. Each central angle for a regular pentagon is <span><span><span>360∘</span>5</span>=<span>72∘</span></span><span>. So, half of that, to make a right triangle with the apothem, is </span><span>36∘</span><span>. We need to use sine and cosine.

Here, first we need to calculate the slope (m)
m = y2-y1 / x2-x1
m = 10 - 4 / 4-2
m = 6/2
m = 3
Now, y - y1 = m(x - x1)
y - 4 = 3(x - 2)
y - 4 = 3x - 6
y = 3x - 2
In short, Your Answer would be: y = 3x - 2
