Visualize the setup of vertical angles. Now, the angle measures allow for this problem to become more difficult. The measurements are 7y-92, y-3, 3x-1, and an unknown angle that is vertical to 3x-1. Are you able to figure out the values of x and y and explain your work? Thank you!

Edit: the y's and x's are opposite from each other...

Edit #2: Take this picture as an example, the measurements are not relative, but the bigger angles are the Y's and the smaller angles are the X's.

Vertical angles are equal    soo   7y-92 = y-3       y= 14.833 degrees

 

All of the angles added should equal 360

 

7y-92  +  y-3   +  3x-1  + 3x-1  = 360

8y - 95   +  6x -2 = 360

8(14.833) - 95  + 6x  - 2 = 360

x = 56.38 degrees

Assumig the "y"  angles are vertical ...we have that

 

7y - 92  = y  - 3       add 92 to both sides....subtract y from  both sides

 

6y   = 89

 

y  =  89/6  =   ( 14 + 5/6  )°

 

So....each  of these vertcal angles measures  (14 + 5/6  - 3)°   =  (11 + 5/6)°  = (71/6)°

 

So....the measure of each of the  other two vertical  angles  =    [ 360  - 2* (71/6) ] / 2 = 

 

[ 360  -  (71/3) ] / 2  =     [ 1080 - 71 ] / 6  =  (168 + 1/6)°  =  (1009 / 6 )°

 

So...

 

3x - 1  = 1009/6

3x  =  1009/6 + 1

3x = 1009/6 + 6/6

3x  = 1015 / 6

x = (1015 / 18)°  = (56 + 7/18)°
