I'm having trouble getting the correct answer! Help please!

Im having trouble getting the correct answer for number 2 - The Correct Anwser is b=17.52

1) Given A = 371528 and B = 443918, calculate C.
angle C= 180- (angle A+B)
C= 180-371528+ 44 3918
C=98deg 5 14


2) Given A = 371528, B = 443918, and a = 15.39, calculate b.
(Sin A)/a = (Sin B)/b
sin(37deg 1528)/15.39=sin(44deg 3918)/b
sin(37deg 1528)b= 3619.447
b=1752.013

Some of your notation is unusual.
3619.447
1752.013

You have symbols ' " * mixed in with the digits.

sin(371528)b = sin(443918)15.39 = 10.8166495 approximately (by calculator).
Hence b = 10.8166495/sin(371528) = 17.87 to four significant figures.
