Step-by-step explanation:

Given, in ΔABC, BC=5 cm, ∠B=60° and AC + AB=7.5 cm. To construct the triangle ABC use the following steps. Draw the base BC = 5 cm. At the point B make an ∠XBC = 60°. Cut a line segment BD equal to AB + AC = 7.5 cm from the ray BX. Join DC. Make an ∠DCY = ∠BDC.  Let CY intersect BX at A. Then, ΔABC is the required triangle.
