A projectile is launched with speed v at an angle θ,the angle being less than 45º.What other angle would give the same range for this projectile launched at the same speed v?
A)2θ
B)0.5θ
C)90° - θ
D)90º - 0.5θ

The range of a projectile launched at an angle θ with a certain speed is the same as that of a projectile launched at an angle (90° - θ) with the same speed. This is due to the symmetry in the projectile motion equations.
