Consider ᐃABC with A ≡ 
, B ≡ 
and 
. If 
= 
= 3; 
= 4, then the angle between the medians 
and 
is -
, B ≡ and . If = = 3; = 4, then the angle between the medians and is -Options
A.π - cos-1
B.π - cos-1
C.cos-1
D.cos-1
Solution
= 0
= 0⇒ angle between
90oLet B be the origin & A
, C 
then M (2ĵ) & D
∴ Angle between
cos θ =
cos θ =
