Please help with this question

For this case we must find the angle "x" of the figure shown.
If we look at the figure, we have to:
AC equals 90 degrees.
So we have to:
[tex]73 + x = 90[/tex]
We clear the value of "x":
[tex]x = 90-73\\x = 17[/tex]
Thus, the value of "x" is 17 degrees.
Answer:
17 degrees
Option A
