Which graph shows a set of ordered pairs the represents a function

First  graph

Step-by-step explanation: A set of ordered pairs is a function if for every x value there is one y value.The set of ordered pairs are function if they pass the vertical line test.If a vertical line is drawn then the line will cut at only one point.

In first graph for all x values we have different y values so the ordered pairs represent a function.

In second graph for x= -2 we have two y values -1 and 1 so the ordered pairs will not represent a function.

(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
