14x-5=65 ( vertically opposite angles)
14x=65+5
14x=70
x=5
z= 180-65= 115

With vertical angles like this, since you know one side is 65 degrees, the opposite side is also 65 degrees.

65*2 = 130 degrees. 360-130=230 degrees. 230/2 = 115
z = 115 degrees

Equation time

(14x - 5) = 65
Add 5 to both sides

14x = 70
Divide each side by 14

x=5
z=115
