(i) A rough sketch can be drawn.
Step 1: Draw DE of 5 cm.
[We will take AE as base since both points have angles so that it will get easier in the later part.]
Step 2: At point E and A we draw 60° and 90° respectively.
Step 3: From point D and E, we draw arcs of measurement of 4cm and 4.5 cm respectively such that they intersect at point R and A.
Step 4: Join AR.
We will draw base of RU = 3 cm
Step 2: At point R and U we will draw angles of 75° and 120° respectively.
Step 3: Taking point R and U as center we draw arcs measuring of 3.5 cm and 4 cm respectively.
Step 4: Join TE.
