For this case we have a pentagon shown, that is, it has 5 sides. By definition, the sum of the internal angles of a pentagon is given by:
540 degrees
So:
[tex]96 + 118 + 104 + x + 115 = 540\\433 + x = 540\\x = 540-433\\x = 107[/tex]
Now we have to:
[tex]A + x = 180\\A = 180-x\\A = 180-107\\A = 73[/tex]
Answer:
Option C
