Solve the problem.A projectile is fired from a height of 7.7 feet with an initial velocity of 116 ft/sec at an angle of 55° with the horizontal. The parametric equations for the path of the projectile are x = (116 cos 55°)t, and y = 7.7 + (116 sin 55°)t - 16t2,where x and y are in feet and t is in seconds. Find the height of the projectile after 4 seconds. Round your answer to the nearest tenth of a foot.
A. 131.8 ft
B. 323.8 ft
C. 124.1 ft
