Hour Hand:
12 hour = 360°
1 hr = 30°
Total Hour above the Clock is $\frac{73}2$ hours
In Minute Hand:
1 Hour = 360°
1 minutes = 6°
Total Minutes covered by $6\times 5= 30$

] | Your approach is correct, but the hour is $6+\frac{5}{60}=\frac{73}{12}$, not $\frac{73}{2}$.
This yields an angle of $\frac{73}{12}\cdot30^\circ$ for the hour hand, and $6^\circ\cdot 5=30^\circ$ for the minute hand.
Thus the end result is $\frac{73}{12}\cdot30^\circ-30^\circ=152.5^\circ$ | The time in minutes (let's ignore the seconds, as there are none here) is 6\*60 + 5 = 365 minutes.
The angle for a hand is `360° * time / (time per 360°)`
The angle for the hour hand is
```
360° * [365 / (12*60)] = 182.5
```
The angle for the minute hand is
```
(360° * 365 / 60) % 360 = 30
```
