The range of a projectile that is launched with an initial velocity v at an angle of a with the horizontal is given by R sin

where g is the acceleration due to gravity or 9.8 meters per second squared. If a projectile is launched with an initial velocity of 1

meters per second, what angle is required to achieve a range of 20 meters? Round answers to the nearest whole number.
