Drag and drop the expressions into the boxes to correctly complete the proof of the polynomial identity.

Step-by-step explanation:

The proof of the polynomial identity shows that the left side equals the right side. To find what comes next, simplify the left side using order of operations (PEMDAS) by doing the exponent first, combing like terms and then simplifying.

simplifies to

(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

you can't solve x because it is 2 linear equation and you only have one equation
