उत्तर


Construction:
Step 1: Drawn a line. Marked P and R on the line such that PR = 7.8 cm.
Step 2: At P, drawn a ray PX making an angle of 60° with PR.
Step 3: At R, drawn another ray RY making an angle of 35° with PR.
Mark the point of intersection of the rays PX and RY as Q.
PQR is the required triangle.
