Answer:
C) 4√3
Step-by-step explanation:
The given triangle is an equilateral triangle. BD is angle bisector.
Triangle BCD is a 30-60-90 degree triangle in the ration of 1:√3:2
Here we are given BC, that is highest length of the side.
So 2x = 8
x = 8/2
x = 4.
BD = √3 x
Now plug in x =4, we get
Height (BD) = 4√3
