Answer 2

Answer:

8:5

Step-by-step explanation:

Step 1: A ray OA is drawn.

Step 2: An arc is drawn with O as a centre.

Step 3:With the same length AB construct another arc from B

Step 4: Construct a perpendicular bisector to another arc which is D.Join OD

∴∠AOC=90

∘

Step 5: Construct a perpendicular bisector from C to another point of the arc .Join OD

∴∠AOD=105

∘

Thus,∠AOD is the required angle making 105
