Please help! I'm writing a test and don't have much time. Step by step please! (20 point)

23x^3+9x^2-5x+1/x^2

Step-by-step explanation:

I hope you don't mind me putting my explanation as a screenshot of this lol

where is the rest of the

step-by-step explanation:

(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
