Which relation is represented by the arrow diagram? mapping diagram of a relation {(2, 0), (6, 3), (0, 0), (–3, 3)} {(–3, 3), (0, –5), (2, 6), (0, 0)} {(–3, 3), (0, –5), (2, 0), (6, 0)} {(3, –3), (–5, 0), (0, 2), (0, 6)}

The left side is the input ( X) values and the right side is the output (Y) values.

The -3 has an arrow pointing to 3, so this becomes (-3,3)

Following the arrows for th other ones you have:

(0,-5), (2,0) and (6,0)

The answer would be the third choice.

c. (3,2,6) is the answer.

(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
