In the triangle ABC
are drawn two sides
of it, BB1 and AA1.
Those half-edges
intersect at point O.
What is the length of
the semicircular BB1
if B10 = a cm?

Respuesta :

Answer:

3a

Step-by-step explanation:

What we have as the point O refers to the centroid of the triangle

The centroid splits the distance between the opposite vertex and the middle of the side length that faces it into two; with the longer side being twice the length of the shorter

So what we have here is that;

B1O is half the length of BO

So, if B1O is a cm, BO would be 2a

So we have the entire side length measure as;

a + 2a = 3a
