Person A is shot out of cannon at 100m/s at 30 degrees above the horizontal on top of a 75 meter tall cliff. After 3 seconds, Person B, standing next to the cannon, shoots an arrow at 200m/s at Person A. At what height does the arrow strike person A, and what angle did he fire at?

2. Relevant equations

X_Ay=75+200 sin(θ) (t-3)+g/2 〖(t-3)〗^2

X_Ax=200 cos(θ) (t-3)

X_By=75+50t+g/2 t^2

X_By=86.6t

3. The attempt at a solution

{(75+200sin(θ)(t-3)+g/2(t-3)^2)^2 + (200cos(θ)(t-3))^2}^1/2 = {(75+50t+g/2 t^2)^2 + (86.6t)^2}^1/2

For some reason I am unable to isolate theta
