The vertices of the triangle are the points where any pair of lines intersect.
We start by setting up the system
Using one of the two equations we can derive the correspondent y value:
So, one vertex is (1, 1)
We choose the other two pairs of lines to find the other vertices:
So, the three vertices are (1, 1), (2, 0), (-1, -3).
Imagine this as a circle. The circle will have a radius of 17mi and the lighthouse will be in the middle. The area of the circle will be the area over which the beacon can be seen.
is the equation for the area of the circle where A is the area.
Now we simply plug in our information
A=
A=907.9
Now we simply plug in our information
A=
A=907.9
