Answer :
Given:
[tex]m\parallel n[/tex]To find:
Value of x in given adjacent angles.
Explanation:
Given angles are adjacents and vertical angles equal.
Solution:
Angle
[tex]\left(9x-5\right)^{\circ}\text{ vertical angle will be \lparen9x-5\rparen}^{\circ}[/tex]So, 9x-5 degree and 6x+20 degree sum to 190 degree.
9x-5+6x+20=180
15x=180-15
x=11
Hence, value of x is 11.
