Two Cooks Standing Side by Side in a Restaurant Pull $\theta$

Two cooks standing side by side in a restaurant pull their beaters out of the dough at the same instant.A glob of dough flies off each beater.Each glob lands on the top of a tin the same horizontal distance away and at its initial height.However,one lands later than the other.The explanation is that they left the beaters at angles $\theta$ ₁ and $\theta$ ₂ such that:

A) $\theta$ ₂ = - $\theta$ ₁.
B) $\theta$ ₁ + $\theta$ ₂ = $\frac { \pi } { 4 }$ .
C) $\theta$ ₁ + $\theta$ ₂ = $\frac { \pi } { 2 }$ .
D) $\theta$ ₁ + $\theta$ ₂ = $\pi$ .
E) $\theta$ ₁ - $\theta$ ₂ = $\pi$ .
