θ is Greek letter theta.
If your question means:
Which equation represents the value θ in a triangle when all other angle information is known?
then
The sum of the angles in a triangle = 180 °
α + β + θ = 180°
Subtract ( α + β ) from both sides of the equation.
θ = 180 ° - ( α + β )
Which equation represents the value of zero in a triangle when and all other angle information is known
