Does anyone know this answer

Work Shown:

9x-73 = 5x-13 ... the two vertical angles are congruent or equal

9x-5x = -13+73

4x = 60

x = 60/4

x = 15

once we know what x is, we can compute the angle expressions involving x

9x-73 = 9*15-73 = 135-73 = 62

5x-13 = 5*15-13 = 75-13 = 62

So this helps confirm we have the proper x value

Now subtract 62 from 180 to get the value of angle z

z+62 = 180

z = 180-62

z = 118

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;
