Given the figure, find the values of x and z.

[tex]\\ \sf\bull\dashrightarrow 9x-67+6x-23=180[/tex]
[tex]\\ \sf\bull\dashrightarrow 9x+6x-67-23=180[/tex]
[tex]\\ \sf\bull\dashrightarrow 15x-90=180[/tex]
[tex]\\ \sf\bull\dashrightarrow 15x=180+90=270[/tex]
[tex]\\ \sf\bull\dashrightarrow x=18[/tex]
Now
[tex]\\ \sf\bull\dashrightarrow z=6x-23[/tex]
[tex]\\ \sf\bull\dashrightarrow z=18(6)-23[/tex]
[tex]\\ \sf\bull\dashrightarrow z=108-23[/tex]
[tex]\\ \sf\bull\dashrightarrow z=85[/tex]
