PROGRAMMING:Height of chimney
It is known that the distance between a person and the chimney is $$a $$, the height of a person's eyes from the ground is $$B $$, the elevation angle when a person looks at the top of the chimney is $$- theta $$, and the height of the chimney is $$h $$.

####Input format
> $$a$$, $$b$$
> $$\theta$$
Note: the unit of $$a $, $$B $$is meter, which is decimal. The unit of elevation angle is degrees, minutes and seconds, where degrees and minutes are integers and seconds are decimals.
####Output format
> $$h$$
Note: the unit of $$h $$is meter.
Requirements: output 2 decimal places, rounding the last place.
####Input sample
```in
27.8 1.2
32 48 59.5
```
####Output sample
```out
nineteen point one three
```
