Question

If angleABC = ADEF, AB = 5 cm, BC =
6 cm, AC = 7 cm, then the length of EF
is:
a.
1 cm
b. 6 cm
C
7 cm
d. 5 cm​

Answer 1

Step-by-step explanation:

DEF∼△LMN

So, AB/ED=AC/EF=BC/DF

Consider AB/ED=AC/EF

5/12=7/EF

By cross multiplication,

EF=(7×12)/5

EF=16.8cm

Now, consider AB/ED=BC/DF

5/12=BC/15

BC=(5×15)/12

BC=75/12

BC=6.25.

Answer 2

Answer:

The length of EF is 8cm because you are counting seraily
