What is 84 degrees 12 feet 15 inches minus 28 degrees 46 feet 38 inches?

Answer 1

In order to achieve the daunting task of completing that calculation, it would be

necessary to borrow (regroup) a foot or two to make some more inches. That's

no problem. We know how to do that, because we know that each foot we borrow

will give us 12 more inches.

But we would also have to borrow (regroup) some degrees to get some more feet.

That's a problem. We don't know how to do that, and we're willing to bet that nobody

does, because angle units and length units can't convert to each other. In all our

years as a math and science nerd, we've never, ever met anyone who was able to

tell us how many degrees tall he was, or how many feet the angles of a triangle

add up to.

So this question is a non-starter. It's not that we can't find the answer. It's that

the question is a jocular flight of fancy, to put it kindly, with no relationship to

legitimate arithmetic, and has no answer. If it had, we'd have no trouble finding it.

Answer 2

To subtract these values, convert all measurements to the same units (either feet or inches). Then, subtract each component separately. In this case, the result is 55 degrees 65 feet 77 inches.
