उत्तर
Construction:
Step 1: Drawn a line. Marked Q and R on the line such that QR = 5.5 cm.
Step 2: At Q, drawn a ray QX making an angle of 90° with QR.
Step 3: At R, drawn another ray RY making an angle of 42° QR.
Marked the point of intersection of the rays QX and RY as P.
PQR is the required triangle.
