Find the angles that are complimentary and supplementary to A= 34º 19' 42"
So, if angle B is complementary to A, then B = 90º - A
ok I get that part.
here is where my book loses me:
so they re-write it like this: B = 90º - 34º 19' 42"
ok, so far so good.
then they rewrite it again: 89º 59' 60" - 34º 19' 42"
they go onto say 90º = 89º 59' 60"
I dont get it. how did they get the 89º 59' 60" ?
Any help would be greatly appreciated. Thanks for your time.
