The range of a projectile fired at an angle with the

The range of a projectile fired at an angle with the horizontal and with an initial velocity of v₀ feet per second is r =¹⁄ ₃₂v₀² sin(2θ) where r is the horizontal distance (in feet) the projectile travels. An athlete throws a javelin at 75 feet per second. At what angle must the athlete throw the javelin so that the javelin travels 115 feet? (Assume 0< 45°. Round your answer to two decimal places.)
