circumcenter of triangle ABC..... vectors

Question

If in a triangle AND. .A=(0,0) B=(33 Sq rt 3) C=(-3 Sq rt 3,3) Then the vector of magnitude 2 Sq rt 2 units directed along A , where O is circumcenter of triangle AND is..

Answer 1

yu left out the komma on B

me assume A:(0,0),B:[33,sqrt(3)], C:[-3*sqrt(3),3]

sqrt(3)=1.7320508075688772935274463415058723669428052538 (approx)

3*sqrt(3)=5.19615242270663 (more or less)

me get straeng triangel: side 1=5.999976, side2=33.045423, side3=38.217164

alfa=146.99538 deg, beta=4.90577 deg, gamma=28.09885 deg

area=53.99999, base=38.2171637, hite=2.82593

rim-leng=77.26256

top=(-5.196124227,3)

Inside serkel: radius=1.39783 & senter=(0.3403,1.4176)

outside serkel: radius=35.08049 & senter=(14.878,31.769)

me dont no bout "circumserkel"
