If a=-1 and b=4, what is the differnce between a to the third power + b?

-1^3 is 1 and 4 so i dont get your question but its 3 or 5.

:

(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

25% is the answer
