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= 180-37°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
