I think it’s B i hope this is correct have a great day :)
Answer:
im thinking number #A but it also d
If you're comparing 1.435 * 10^(-3) mm to 1.435 * 10^3 mm, then the more reasonable measurement is 1.435 * 10^3 mm since,
1.435 * 10^3 mm = 1435 mm = 1.435 meters
1 meter is about 3.28 feet approximately
So 1.435 meters is slightly larger (about 4.708 feet) which is a fairly reasonable distance between the tracks on a railroad.
-------------------
Something like 1.435 * 10^(-3) mm is equal to 0.001435 mm, which is far less than 1 mm.
Perpendicular bisectors are segment that passes through the mid point of a triangle, while altitude is the perpendicular distance from the base to the opposite vertex.
Log25 (5•25) = 3 over 2 aka 3/5
