1) Horizontal velocity = 20 x cos 53 degrees = 12.0 m/s
Vertical velocity = 20 x sin 53 deg = 16.0 m/s

2) Horizontal velocity = 10 x cos 68 = 3.75 m/s
Vertical velocity = 10 x sin 68 = 9.3 m/s

This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
