PROGRAMMING:campaign in champaign
Our army encountered the enemy in the plain, and our artillery aimed at the enemy and fired.
Please write a program to input the initial velocity of the shell $$v_ 0 $$and range $$x $$, output projectile's firing angle $$\ alpha $$.
####Input format
>Initial velocity $$V $$(M / s)
>Range $$x $$(m)
####Output format
>Angle of fire $$\ alpha $$(degrees, minutes and seconds)
Requirements: the shooting angle shall not be less than 45 degrees. Second output 2 decimal places, the end of 4 rounded.
####Input sample
```in
seven hundred and sixty point eight
forty-eight thousand six hundred and thirty-one point five three
```
####Output sample
```out
62 17 14.81
```
Note: acceleration of gravity $$= 9.8, PI $$= 3.1415926535897932384626
