Triangle ABC has circumcenter O. If AB = 10 and [OAB] = 50 find the circumradius of triangle ABC.
+1693 Triangle ABC has circumcenter O. If AB = 10 and [OAB] = 50 find the circumradius of triangle ABC.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Let ΔABC be an isosceles triangle with base AB = 10.
Let the midpoint of AB be M
OM = (2 * 50) / 10 = 10
Circumradius R = sqrt(OM2 + AM2)
R = √125
