In ΔABC, DE || BC so that AD = 2.4 cm, AE = 3.2 cm and EC = 4.8 cm. Then, AB = ?
By Basic Proportionality Theorem
If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio. ..
In Δ ABC, DE ∥ BC
DB = 3.6 cm
AB = AD + DB
AB = 6 cm
