Question

Two angles have measures of 63°15'47" and 116°44'13". The angles are

complementary
supplementary
neither complementary or supplementary

Answer 1

complementary means they add to 90 degrees
supplementary means they add to 180 degrees

when you add an angle with degrees, minutes, and seconds, it is a lot like adding two times together... if the seconds add to more than 60, you "carry"... so you have some seconds and carry the extra minute. If the seconds add exactly to 60, then the sum of the angles has an extra minute (1 minute = 60 seconds), but 0 seconds...

It's exactly like adding 1 min 30 seconds to 2 min 30 seconds... you get 4 minutes total.

Just add these two angles and see what you get.

Answer 2

so supplementary?

Answer 3

That's what it looks like to me...

13 sec + 47 sec = 1 min 0 sec
carry the 1 min + 15 min + 44 min = 1 degree, 0 min, 0 sec
carry the 1 deg + 63 + 116 = 180 degrees

Answer 4

thats what i got, thanks! ^^
