Icoseles is a type of triangle.
The correct spelling is "isosceles" (a triangle with two sides of equal length).
I'm pretty sure it's an icoseles triangle because they have two equal sides or an equilateral with all the sides the same.
Assuming this would have been taken in May and January, we have some simple trig to do.1 second is 1/3600th of a degree, so 1/1200th of a degree is the parallax. We will need to use the diameter of the Earth's orbit, which is about 300 million kilometers. If we draw this, we see that we have an icoseles triangle. We bisect the top angle, which bisects the bottom side. We have two right triangles now, and we can use the sine of 1/2400 of a degree, which is 150,000,000/the distance. We divide this number by 150,000,000, getting 1/distance = 4.848 times 10^-14. We do this answer to the -1 to get an answer for distance, or 2.06*10^13 km, which is equal to 68,754,935 light years. This is for a perfect 3 seconds, so there is obviously a margin of error. However, I am thirteen years old and have never done this before, so it may be wrong. When stuck with a problem like this, my suggestion is to draw a picture.-WestonA+57.7 trillion miles
