100 degrees
complementary angles are defined as 90 degrees - the given angle so 90-80=10 10 degree angle is complementary to an 80 degree angle
A ten degree angle is complementary to an eighty degree angle. Complementary angles add up to 90 degrees, so 10 + 80 = 90.
80 degree
80 degrees is an acute angle because it is greater than 0 but less than 90 degrees
Complementary angles total 90o so 90 - 80 = 10; the complementary angle is 10o.

A ten degree angle is complementary to an eighty degree angle. Complementary angles add up to 90 degrees, so 10 + 80 = 90.
Two angles are complementary of they both add up to 90 degrees. Therefore the complement of eighty degrees would be 10 degrees. (80+10=90)
Any angle between 0 degrees and 90 degrees is called an "acute" angle.
OBTUSE
sine 10. Use the cofunction with the complementary angle.
80 degree
80 degrees is an acute angle because it is greater than 0 but less than 90 degrees
The smaller angle is 20 degrees and the larger is 70 degrees. Complementary angles total 90 degrees. Let's call the smaller angle A. The other angle is 3A + 10. The sum of both angles is 90, so 4A +10 = 90, 4A = 80, A = 20. The larger angle is 3(20) + 10 = 70.
You subtract 90 degrees minus 80 degrees 25'. Note: You should convert the 90 degrees to 89 degrees and 60 minutes first, that way you can easily subtract degrees and minutes.
