Fill in the missing word: an unknown or chargeable quantity is called a (n)

I believe the answer would be variable, because it is unknown which is very common for variables.

Plus, the variable definition (loose) is an unknown factor that can change in a trial.

I hope this helps!

(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
