Answer :
step1 draw a circle of radius 4.2 cm with center as O. step 2 take a point A on the circle and join OA . Draw a perpendicular to OA at point A.
step3 DRAW a radius OB making an angle of 90 degree with OA.
step4 draw a perpendicular to OB at point B. let both the perpendicular intersect at point P.PA and PB are required tangents at an angle at 45 degree.
