Looks like you end up with a triangle with sides
13, 13, and 12.
mmmhhh, two of the sides are equal, and the third is almost equal to the other two.
So it is "almost" an equilateral triangle, and the angles should be "near" 60°
How can you NOT be sure about it being acute and isosceles ?
A ship in calm seas steamed 13 km in one direction, turned and steamed 13 km in another
direction, and then returned 12 km back to its original position. The captain then plotted
the ship’s course on a nautical chart. She asked her first officer to look at the chart and
describe the ship’s path. Did the first officer describe it as an acute, obtuse, or right
triangle? Then the second officer said she could further identify whether the path was
scalene, isosceles, or equilateral. What did she determine?
I'm not sure, but I think it might be acute; isosceles?
