Question

Steps for the construction of a triangle ABC in which AB=5.8cm, BC+CA=8.4cm and $\angle B={60}^{\circ }$ is given below.Choose the correct order.

1.Join AC
2.From the segment BX,cutoff line segment BD of length 8.4cm.Join AD
3.Draw the perpendicular bisector of AD and let it meet BD at C.
4.Draw a line segment AB of length 5.8cm
5..Draw a line segment BX , sufficiently large such that $\angle ABX={60}^{\circ }$
