I’m having trouble getting the correct answer for number 2  The Correct Anwser is b=17.52 1) Given A = 37°15’28” and B = 44°39’18”, calculate C. angle C= 180 (angle A+B) C= 18037°15’28”+ 44° 39’18” C=98deg 5’ 14” 2) Given A = 37°15’28”, B = 44°39’18”, and a = 15.39’, calculate b. (Sin A)/a = (Sin B)/b sin(37deg 15’28”)/15.39’=sin(44deg 39’18”)/b sin(37deg 15’28”)b= 36’19.447” b=17°52’.013

Some of your notation is unusual. 36’19.447” 17°52’.013 You have symbols ' " * mixed in with the digits.

sin(37°15’28”)b = sin(44°39’18”)15.39’ = 10.8166495’ approximately (by calculator). Hence b = 10.8166495’/sin(37°15’28”) = 17.87’ to four significant figures.
