Answers (1)


The steps of construction are as follows:

Step 1: Draw a line segment BC of 7cm length. Taking the help of protractor make an \angle XBC = 75^{\circ}.

Step 2: Now, cut a line segment BD having 13 cm on BX which is (AB+AC).


Step 3: Now, join CD.

Step 4: Draw a perpendicular bisector of CD to intersect BD at a point A. Join AC. Then ABC is the required triangle

Hence, the required triangle is ABC.
