We know from Euclidean Geometry and the properties of a centroid that GC=2GM. Now GM=sin60*GA=

. Hence CM=GC+GM=3*

. Now, since GM is normal to AB, we have by the pythagoeran theorem that:

Hence, we calculate from this that AC^2= 28, hence AC=2*

=BC. Thus, the perimeter of the triangle is 2+4*

.
Answer:
18,480 feet
Step-by-step explanation:
3 times 24 is 48% therefore its D.
Y=-2x+7 That is the equation written in y=mx+b formula
