<span>The meeting point of the 3 </span>perpendicular bisectors<span> of a triangle's sides is called </span><span>the circumcenter.
</span><span><span>The circumcenter of an </span>acute triangle<span> is always </span>inside<span> the triangle.
so the answer is "a"

<u><em>Density= Mass divided by Volume</em></u>, but you're trying to find Volume so you apply Algebra and get <u><em>Volume= Mass divided by Volume.</em></u>
Volume= 0.5592841163 [kg/m (power to the 3)]
You should round it up
-24 + 12d = 2(d - 3) + 22
-24 + 12d = 2d - 6 + 22
-24 + 12d = 2d + 16
12d = 2d + 40
10d = 40
d = 4
Hope this helps.
Using the (x,y) coordinate or unit circle concept, find which quadrant the vector is in by the signs of x and y. Take the arcTan( y/x) for its reference angle, then draw the vector in that quadrant.
