Question

in ∆ ABC angle A=60° BC,=12 cm find the cricumradius of triangle​

Answer 1

Step-by-step explanation:

ABC is a right angled triangle with angle ABC = 90°.

So, AC = [√{(5^2) + (12^2)}] cm = 13 cm.

We know, for any right angled triangle, the circumcentre coincides with the midpoint of the hypotenuse.

So, length of radius of the circumcircle = (13 / 2) cm = 6.5 cm.
