Answer 2

Answer:

Step 1 : Draw a circle of radius 4.5 cm with center O.

Step 2: Take a point A on the circle join OA.

Step 3: Draw a perpendicular to OA at A.

Step 4: Draw a radius OB making a angle 120° (180° −60° ) with OA

Step 5: Draw a perpendicular to OB at B. Let these both perpendicular meet at P.

∴ PA and PB are the required tangents with angle of inclination 60° .
