Can someone please check my answers .Thanks!

1.)convert the angle theta =40deg 10minutes 25 seconds to a decimal in degrees.round to 2 decimal places

i got 40.173---40.28

2)convert 18.255 degrees to DMS form and then round to the nearest second.
I got 18 deg 15minutes 18 second

3.)given theta =53 degreees find one positive and one negative coterminal of theta.
I got 307 and -307

#1 I got 40.1736; rounding to 2 decimals = 40.17 (.28 is one key to the right. Typo?) #2 We agree on this one #3 is wrong: Your neg coterminal is 53-360 = -307 (this one you got okay) Your pos coterminal is 53+360 = 413 (yes, really. :-) http://hotmath.com/hotmath_help/topics/coterminal-angles.html
