Answer:
[tex]x=46[/tex]
Step-by-step explanation:
If two angles lie on the same line, they should add up to 180 degrees.
That means 69 + z = 180.
z = 180 - 69
z = 111
The three angles in a triangle should add up to 180 degrees.
23 + x + z = 180
Substitute 111 for z.
23 + x + 111 = 180
x + 134 = 180
x = 180 - 134
x = 46
