The graph plots for equations a, b,c, and d.

which pair of equations has (2, 12) as its solution?

Hence, Graph B and C has ( 2 , 12 ) as its solution.

Step-by-step explanation:

Given:

Graph Plot for A     {Black line in graph}        

Graph Plot for B     {Green line in graph}

Graph Plot for C     {Red line in graph}

Graph Plot for D     {Blue line in graph}

To Find:

Which pair of equations has (2, 12) as its solution?

Solution:

A solution of pair of line is the point which satisfies both the equation. Hence it is also the intersecting point of two lines.

Therefore,

Graph Plot for B     {Green line in graph}

and

Graph Plot for C     {Red line in graph}

has the point of intersecting on ( 2 , 12 )

Hence, Graph B and C has ( 2 , 12 ) as its solution.

(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
