Question

D and e are the midpoint of side ab and ac respectively if BC equal to 5.6 cm and angle B equal to 72 degree compute De​

Answer 1

Answer:

It is given that,

D and E are the midpoint of sides AB and AC

BC=5.6 cm and ∠B=72o

To find:  DE

In △ABC,

D and E are the mid point of the sides ABand AC

⇒DE∥BC  and  DE=21BC[ Using mid point theorem ]

∴DE=21×5.6=2.8 cm
