What is the answer to this??
Firdavs [7]

Answer:

x=3

z=65

Step-by-step explanation:

6x+97 and 14x+73  are vertical angles which means they are equal

6x+97= 14x+73

Subtract 6x from each side

6x-6x+97= 14x-6x+73

97 = 8x +73

Subtract 73 from each side

97-73 = 8x+73-73

24 = 8x

Divide each side by 8

24/8 = 8x/8

3 = x

Now we need to find z

6x+97  and z are supplementary angles which means they add to 180

6x+97 +z = 180

6(3) +97 +z = 180

18+97+z=180

Combine like terms

115+z = 180

Subtract 115 from each side

115-115 +z=180-115

z = 65

Write the standard equation of the line that passes through the point (-1,12) and has the same slope as a vertical line
Rom4ik [11]
Vertical lines have undefined slope. They are not y=mx+b equations, but simply x= equations.

This line passes through the point (-1,12) has an x-value of -1. Therefore the equation of the line is simply  x=-1
