Two rocks are thrown simultaneously from the top of a very tall tower with identical speeds of v = 5.90 m/s, but in two different directions. (See figure.)

One of them is thrown with an angle of 17.4 degrees below the horizontal, and the other one is thrown at an angle of 57.6 degrees above the horizontal. How far will the rocks be from each other after 5.45 s? (Neglect air resistance and assume that the rocks will not hit the ground.)
