ii) At B draw an angle DBX = 75 deg [Angle may be constructed with protractor or with compass]

iii) In BX cut off an arc of radius = 7 cm; let this point be C

iv) Join CD

v) Using compass draw a perpendicular bisector for CD, which meets BD at A.

vi) Join AC; ABC is the required triangle.

Reason:

Since A is a point on the perpendicular bisector of CD, by locus theorem it is equidistant from the end points C & D of the line segment CD. Hence AC = AD.

Thus BD = BA + AD = BA + AC = 13 cm
