There is no choice on your list that must represent an odd integer.
If 'z' is an even integer, then (z-1) and (z+1) must both be odd integers.

Answer:
30°
Step-by-step explanation:
53°+97°+x = 180°
The sum of three angles must equal 180°
Solve the equation.
150°+x = 180°
x = 180°-150°
x = 30°
Therefore, x = 30°
3:4, 3 to 4, 3/4
