已知∠a=50°17′42〃,求∠a的补角和余角的度数。

Answer 1

补角=180°-50°17′42〃=179°59'60''-50°17′42〃=129°42'18''
余角=90°-50°17′42〃=89°59'60''-50°17′42〃=39°42'18''

Answer 2

余角=90°-50°17′42〃=89°59'60''-50°17′42〃=39°42'18''

Answer 3

补角为 129°42'18"
余角为 39°42'18"

Answer 4

129*42'18" 39*42'18"

Answer 5

补角为129°42′18〃，余角为39°42′12〃
