9. use gauss-jordan elimination to find all solutions to the system of linear equations i-2r2-3r3 -1 12 2t3 i1 +3r2+5x3 1 2 -

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

answer is 12345678900987654321234567890987654321
