Answer:
[tex]w=\frac{180-76}{2}[/tex]
=> Please see the picture I attached for a better understanding
According to vertical angle theorem, when two straight lines intersect, they form two sets of linear pairs with congruent angles
so A = 76
The angle of a straight line is 180 degree
Therefore, we can get this equation
[tex]180-w-w=76[/tex]
=> simplify, and you will get the answer
=>
[tex]w=\frac{180-76}{2}[/tex]
