1. jim_thompson5910

Complementary angles add to 90 degrees. So if z is complementary to theta, then $z+\theta=90$, which means that $z=90-\theta$

2. ZeroAT

The question is theta = 63 degrees, 4 min and 15 seconds

3. shaishai

90 degrees minus theta is the complimentary angle, 180 degrees minus theta is the supplementary angle

4. shaishai

there are 60 minutes in a degree, and 60 seconds in one minute

5. jim_thompson5910

theta = 63 degrees, 4 min and 15 seconds 90 - theta = 90 - (63 degrees, 4 min and 15 seconds) 90 - theta = (89 degrees 59 minutes 60 seconds) - (63 degrees, 4 min and 15 seconds) 90 - theta = 26 degrees 55 minutes 45 seconds So the complementary angle is 26 degrees 55 minutes 45 seconds
