Question

please someone answer this question I need the answer urgently ​

Answer 1

Step-by-step explanation:

From given triangle, points D and E are on the sides AB and AC respectively such that DE∣∣BC.

AD=3.6 cm, AB=10 cm and AE=4.5 cm.

By Basic Proportonality Theorem:

DB

AD

=

EC

AE

Here DB=AB−AD=10−3.6=6.4 cm

⇒EC=

3.6

4.5

×6.4

or EC=8 cm

And, AC=AE+EC

AC=4.5+8=12.5 cm
