How to solve x=7 linear equations

(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

the answer is a. 72. but i cant answer with less than 20 characters so here's some random text talking about it.

(f+g)(x) = 3^x+10x+4x-2

      =3^x +14x-2

choice b
