Question

Please solve question no 5 and 6....... ​

Answer 1

Answer:

The remaining sides are BC and EF:

BC = 25/4 cm or 6.25 cm

EF = 84/5 cm or 16.8 cm

Step-by-step explanation:

Given,

triangle ABC is similar to triangle EDF.

so,ratio of their corresponding sides will be equal

by SSS similarity criteria.

so, AB/ DE = BC/DF = AC/EF

putting the values given in question,

5/12 = BC/15 = 7/EF

comparing 5/12 = BC/15

so, BC = (5×15)/12

BC = 25/4 cm or 6.25 cm

now comparing 5/12 = 7/EF

so, EF = 7×12/5

EF = 84/5 cm or 16.8 cm
