Assuming theta is in QI, find theta for sin(theta)=.8081,...

[1337455]

i have finals in trig and I have noone to review with for the test on tuesday...
I need to know if these answers are correct so if I could get like 2 ppl to confirm I would feel very satisfied
Assuming theta is in QI
a. sin(theta)= .8081 then, theta= 53.9 degrees to the nearest tenth
b. tan(theta)= 1.135 then, theta= 48.67 degrees to the nearest hundredth
c.sec(theta)= 2.107 then, theta= 61 degrees 40' 12''
d.csc(theta)= 3.05 then, theta= 19 degrees 8'

a) I get the same value.
b) Close. Are you working from a calculator or from tables?
c) Close.
d) If you're only supposed to go to "minutes" (rather than "minutes and seconds"), then I get the same value.
