Question

how do you multiply 981 and 32°51'

Answer 1

multiply 981 to 32 then multiply 981 to 51 then add them

Answer 2

okie dokie, so you're trying to see what's 981*sin(32°51').

well, there are 60 minutes in 1 degree, and 60 seconds in 1 minute, so this one is 32° and 51 minutes, if we convert the minutes to degrees that'd be 51/60 or 0.85, so 32°51' is really 32° + 0.85°, or 32.85°.

981 * sin(32°51') => 981 * sin(32.85°) => 532.13514746651950273164 or about 532 if rounded up.
