hey
I'll answer ur new question
the question is
1)(b) The angle of refraction as the ray entered side AB of the prism was 22°.
(i) On Fig. 2.1, draw in the refracted ray from point D as accurately as possible.
You just need to draw the angle 22° from point D..
(ii) Mark the point E, where the ray meets side AC. Draw the normal at point E.
