Angular dimensions on engineering drawings are expressed as follows:
(c) Degrees, minutes and seconds e.g. 30° 40' 20".
For clarity a full space is left between the degree symbol and the minute figure also between the minute symbol and the second figure.
In the case of an angle less than one degree it should be preceded by 0°, e.g. 0° 25'.
Figure 14.17 shows various methods of dimensioning angles.
