Question

there is a triangle AD 10cm Ae 10cm what's the length of de if the triangle is icos else ​

Answer 1

Answer:

Let AE be x cm.

Then, EC=18−x cm

Since, DBAD=ECAE

Therefore,

32=18−xx

36−2x=3x

5x=36

x=7.2 cm

Answer 2

Answer:

Let AE be x cm.

Then, EC=18−x cm

Since,

DB

AD

=

EC

AE

Therefore,

2

=

18−x

x

36−2x=3x

5x=36

x=7.2 cm

Hence, this is the answer.
