Solution



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.
