A projectile is fired with an initial velocity of 250 m/s at a target located at a horizontal distance of 4 km and vertical distance of 700 m above the gun. Determine the value of firing angle to hit the target. Neglect air resistance

consider the equations for horizontal and vertical distances.
250cosθ * t = 4000
250sinθ * t - 4.9t^2 = 700
solve for θ, using t = 16/cosθ
