*draw a line BC using a ruler of 5.2 cm
*place ur D on point B and Mark the point on 60 degree
*take your ruler and draw a line between point B and the 60 degree point and extend the same line
*angle A+angleB+angleC=180(by a theorem)
100+60+angleC=180
160+angleC=180
angleC=180-160
therefore angleC=20degree
*take your D and place it on point C and Mark a point of 20 degree
*draw a line between pointC and 20degree point and extend it till intersection
*mark the intersection point as A
*place ur D on point B and Mark the point on 60 degree
*take your ruler and draw a line between point B and the 60 degree point and extend the same line
*angle A+angleB+angleC=180(by a theorem)
100+60+angleC=180
160+angleC=180
angleC=180-160
therefore angleC=20degree
*take your D and place it on point C and Mark a point of 20 degree
*draw a line between pointC and 20degree point and extend it till intersection
*mark the intersection point as A
