उत्तर
Construction:
Step 1: Drawn a line. Marked P and Q on the line such that PQ = 6 cm.
Step 2: At P, drawn O ray PX making an angle of 115° with PQ.
Step 3: At Q, drawn another ray QY making an angle of 40° with PQ.
Marked the point of intersection of the rays PX and Q Y as R.
PQR is the required triangle.
