Question

If in Triangle ABC, DE || BC, AB=3.6 cm, AC=2.4 cm and AD=2.1 cm, then the length of AE is

Answer 1

Answer:

according to Thales,'s theourium

AB/AD=AC/AE

SO , 3.6/2.1=2.4/AE

12/7=2.4/AE

AE = 1.4 cm

Answer 2

Answer:

1.4

Step-by-step explanation:

we know that

DE PARALLEL TO BC

then triangle ABC is similar to triangle ADE

ACCORDING to basic proportionality therom

AB/AC=AD/AE

3.6/2.4=2.1/AE

SO AE=1.4
