Which equation shows y= -1/2x+4 is in standard form? a) x+2y=8 b) x+2y=-8 c) 2x-y=8 d) 2x+y=8

The standard form:

We have:

     multiply both sides by 2

     add x to both sides

(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

where are the images of the functions i can only see the question you typed.
