Question 187738
    Can someone help me with this please. If the measure of an angle is 23 degrees 17' 18", what is the measure of its supplement?
.
Two angles are "supplementary" if the sum of the two angles equals 180.
.
180 00' 00"
 23 17' 18"
.
Borrowing from the 180 and then subtracting we have:
179 59' 60"
 23 17' 18"
-----------
156 42' 42"
.
That is,
156 degrees 42 minutes and 42 seconds
