In , D and E are points on side AB and AC respectively such that
and AD: DB = 3 : 1. If EA = 3.3 cm, then AC =
From the given figure ΔABC, DE || BC.
Let AC = x cm.
We know that basic proportionality theorem states that if a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, then the other two sides are divided in the same ratio.
Then
⇒ x = 4.4 cm
∴ AC = 4.4 cm
