Which of the following angle cannot be constructed just with the help of a ruler and a compass?

The angles which cannot be constructed by bisecting the standard angles (i.e., multiple of 15°) like 30°, 45°, 60°, 90°, or 180° are the angles that are not possible to be constructed using just a compass and a ruler.

11.25° = $\frac{22.5°}{2}=\frac{\left({\displaystyle \frac{45°}{2}}\right)}{2}$ ,
202.5° = 180°+22.5°=180°+$\frac{45°}{2}$
315° = 180° + 90° + 45° or 360° − 45°

But the angle of 70° cannot be constructed using a ruler and a compass.
