Find the midpoint of the line segment joining the points R(1,3) and S(-3,6)

(-1, 4.5)

Step-by-step explanation:

[(1-3)/2, (3+6)/2]

= (-2/2, 9/2)

= (-1, 4.5)

(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

a is the correct
