Complement of 72 40'
Answers
Answer:
Complement of 72 40' is 17° 20'.
Explanation:
When two complementary angles are added together, they total 90 degrees. Because this is also the measure of a right angle, it may help to think of complementary angles as what you get when you draw a line that divides a right angle into two separate angles. If you are given the measure of one angle, you can use this relationship - which adds up to 90 degrees - to find the complement of that angle.
Subtract the measurement of an angle from 90 degrees to find its complement. The complement will be the end result.
Subtract the first angle measurement from 90 degrees. The result is the complementary angle measurement.
Complement of 72° 40' = (90° - 72° 40') = 17° 20'.
