                (i)    75o

Answers (1)

Steps to construction to follow:

construction 8

Step 1: Draw a ray OY.

Step 2: Now, taking O as the centre draw an arc ABC.

Step 3: On taking A as a centre, draw two arcs B and C on the arc ABC.

Step 4: Now, taking B and C as centres, arcs are made to intersect at point E and the \angle EOY = 90^{\circ} is constructed.

Step 5: Taking A and C as centres, arcs are made to intersect at D.

Step 6: Now, join OD and hence, \angle DOY = 75^{\circ} is constructed.

Hence, \angle DOY is the required angle.
