उत्तर
Construction:
Step 1: Drawn a line. Marked B and C on the line such that BC = 8 cm.
Step 2: At C, drawn a ray CY making an angle of 40° with BC.
Step 3: With C as centre, drawn an arc of radius 6 cm to cut the ray CY, marked the point of intersection as A.
Step 4: Joined AB.
AB is the required triangle.
