I need help with these 2 problems please. and please make it legible.

Find the angle between the vectors u = 1/5 i 9i and v = 5 i +j 3k. The angle between the vectors is 6 m D radians. (Do not round until the final answer. Then round to the nearest hundredth as needed.) Agun with a muzzle velocity of 1160 ft I sec is fired at an angle of 17 above the horizontal. Find the horizontal and vertical components of the velocity. The horizontal component of the velocity is D ft / sec. (Round to the nearest integer.)
