Which of the following is the best approximation for the measure of angle A if you are given sin A = .312?
a. 17.32°
b. 18.18°
c. 71.82°
d. 21.34° 
Get a calculator, make sure it is in degree mode and find
the key that reads:



Then use that key with .312 and you'll get 18.17980119°, so
the nearest to that is choice b


Which of the following is the best approximation for the measure of angle B if you are given tan B =  
a. 36.87° 
b. 53.13° 
c. 45.78° 
d. 38.66° 

You forgot to tell us what tan B equals.  But you'd use the
 key on your calculator.

if it was .75, or .750 then the correct answer is a
if it was 1.333 then the correct answer is b
if it was 1.028 then the correct answer is c
if it was .8 or .80 or .800 then the correct answer is d
