Question

construct a triangle ABC in which BC=7cm angle B=75 degree and AB+AC=13cm

Answer 1

Steps of construction:
Step 1: Draw a line segment BC of 7cm.
Step 2: At point B, construct an angle XBY such that it is equal to 750 (Take the help of a compass)
Step 3: A line segment BD = 13cm is cut on BX which is equal to (AB + AC).
Step 4: DC is joined and ∠DCY = ∠BDC is made.
Thus, ΔABC is the required triangle
